Topic: xEV thermal management – heat transfer improvement requirements

Abstract and Biography


Market analysis are clearly showing increased electrification of powertrains and especially in 2030, Battery Electric Vehicle (BEV), market could be as high as 30%. The key element for the electrification is the battery. Among the different challenges for developing a battery pack for HEV (Hybrid Electric Vehicle) and BEV, the cooling method can account for up to 5-10% of the total cost of the battery well as impacting weight and packaging volume. With the forecasted cost reduction of the battery cell, the required increase in power and energy density, the cooling method plays an even greater role. Electric motor and power electronics thermal management is another important aspect of the xEV successful integration.

The presentation will show different methods to manage temperatures of electric components on xEVs and how to handle all the cooling and heating requirements depending on the driving conditions thanks to the help of multi temperature cooling circuits and advanced thermal control methods (such as Model Predictive Control and electronic Horizon) requiring reduced order thermal models.

Improving the cooling performance for durability (battery ageing) improvement, ultra fast charging capabilities (as enabler for increased BEV market penetration), cost reduction, performance (electrical power) increase will be discussed

Topic: Phenomenon and mechanism of spray cooling and supercritical-pressure fluid Impingement cooling on micro/nano hybrid structures

Abstract and Biography


Spray cooling is an efficient cooling method forhigh power device heat management.Spray cooling is particularly favorable because of its high heat flux dissipation capability, precise temperature control and reliable long-term stability. Micro, nano and micro/nano structures were fabricated to study the effects of these structures on the spray cooling heat transfer enhancement. The droplet impingement cooling wasnumerically studied first to identify the flow and heat transfer details and to offer insights into the spray cooling heat transfer mechanisms. Through the advanced experimental method, the impact flow and phase change of single microscale droplet were investigated to reveal the heat transfer enhancement mechanisms of spray cooling. The boiling phenomenon of the microscale droplet after impact was studied theoretically by combining the droplet impact process and the following phase change process. Then, the wetting characteristics and heat transfer performance of nano-structured surfaces and micro/nano hybrid surfaces were studiedexperimentally, which showed much higher HTC and CHF with these structured surfaces. The spray cooling heat transfer was also studied experimentally in a closed-loop spray cooling system using arefrigerant as the working fluid.

In the process of convection heat transfer of fluids at supercritical-pressures the phase changedoes not happen.Therefore, there is no dryout phenomenon and CHF for impingement cooling with the supercritical-pressure fluid. Jet impingement cooling with CO2at supercritical pressureswas studied experimentally and numerically. It was found thatthe average HTC of jet impingement cooling of CO2at SCP is rather high than that with spray cooling when the cooling area is not very large compared to the nozzle diameter. Spray cooling consumes less coolant compared to jet impingement cooling with the same heat flux.This studyprovides useful guidance on the heat transfer enhancementandheat transfer mechanisms for spray cooling and supercritical-pressure fluid impingement cooling on different structured surfaces.

Topic: A new perspective on internal forced and mixed convection heat transfer

Abstract and Biography


Heat transfer through a smooth circular tuberemains one of the most important heat transfer problemsin internal convetion. Depending on the method of heating/cooling (constant heat flux or constant wall temperature) the flow regimes might be forced convection or mixedconvection. This will significantly influence parameters such as the development of the hydrodynamicandthermal boundary layers and entrance lengths, the local-and average heat transfer coefficients, as well as the local and average pressure drops.

Extensive theoretical work was done from which the above-mentioned parameters were estimatedfor forced convection conditions, but it was unfortunately not necessarily verified byrigorous experimental work. Alittleexperimental and theoretical work has been done for mixed convection heat transfer; however,the focus was mainly on the laminar flow regimeand very little work has been done for the transitional flow regime.

It was therefore the purpose of this study to give a new perspective on forced and mixed convection heat transfer in smooth circular tubesby conducting rigorous experiments and compiling an experimental database which were orders of magnitude largerthan previous databases. Some of the main new perspectives that were developedfrom the resultsare:

  1. A longer thermal entrance length is required if the flow is simultaneously hydrodynamically and thermally developing.
  2. The fully developed forced convection laminar Nusselt number is not constant at 4.36, but is a function of Reynolds number for Reynolds numbers greater than 600.
  3. Free convection effects were found to decrease the thermal entrance length.
  4. The width of the transitional flow regime decreased and the transition gradient increased as the flow developed along the tube length. Once the flow was fully developed, both the width of the transitional flow regime and transition gradient remained constant.
  5. Free convection effects caused the width of the transitional flow regime to decrease and the transition gradient to increase. At very high Grashof numbers, the transitional flow regime even became negligible and the flow regime changed from the laminar flow regime to the quasi-turbulent flow regime at the next Reynolds number increment.


Prof Josua Meyer, was in 2002, appointed at the University of Pretoria as professor, and Head of Mechanical and Aeronautical Engineering (1900 students), and in 2004, Chair of the School of Engineering (7000 students). He is now serving his fourth terms for both Head of Department and School Chair.

He is leading the Clean Energy Research unit that he established with a broad focus on thermal sciences and fluid flow, but with a narrower focus on heat exchangers. His heat exchanger work focused on fundamental work of flow in the transitional flow regime, nanofluids, and condensation. On an applications level his work focuseson thermal-solar-, wind-and nuclear energy. He has grown this group to approximately 50 full-time graduate students and 10 staff members. During this time,he also established various labs with state-of-the-art instrumentation and designed and constructed (with his group members) more than 12 unique experimental set-ups.

He has received 11 different national teaching awards from three different universities, as well as an international award, in 2013, for “Best professor in mechanical and aeronautical engineering”. He has won more than 45 research awards including 23 awards for best article of the year or best conference paper. For his research he has won the following national and international awards: Thomas Price Award, Rand Coal Award, South African Institute of Mechanical Engineers Medal, LT Campbell-Pitt Award, Literati Award, Chairman’s Award of the South African Institute of Air-conditioning and Refrigerationand Will Stoecker award.

Topic: A perspective on the current and future roles of additive manufacturing in process engineering with an emphasis on heat transfer

Abstract and Biography


Numerous process engineering applications are now exploiting additive manufacturing (AM) to produce more advanced concepts that are delivering demonstrable performance improvements. In the subject area of heat transferfor example, this includes the fabrication of bespoke heat exchangers, recuperators and heat pipes [1,2,3], some of whichare specifically being used to solveproblems in real industrial settings. In this talk, three specific examples of AM that are being researched in the Process Intensification Group(PIG)at Newcastle University will be discussed, and then abstracted/generalised to provide a perspective on how AM can be best exploited now and in the future.Additionally, this talk will also provide an overview of the current state of AM, and will provide a brief overview of each of the main AM technologies and their major advantages, disadvantages and current/potential applications.

AM might presently be better considered as a tool like any conventional manufacturing processrather than a one-size fits all approach, whereas in the future, AM might becomea moreintegrated toolfor the fabrication of plant equipment that hybridises multiple unit operations. The main work prior to the realisation of the latter will be increasing the knowledge-base of PI-technologies –several EU projects are already working toward this goal (examplesinclude IbD andPRINTCR3DIT) [4,5]. Theprojectsin the PIGthat will be discussed that are also relatedto this research goal are: (1) the miniaturisation of the Torbed® technology (Figure 1a) for screening adsorbents for carbon capture (in collaboration with Torftech Group Ltd., HeriotWatt University and University of Sheffield)[6], (2) proposing novel heat pipe wick geometries that could potentially fully optimise thethermal performanceof heat pipes(work commissioned by HiETA[7]and SES Engineering Services), and (3) producing bespoke and complex reactor geometries that can be used in conjunction with dynamic reactor operation (e.g. oscillatory flow) to unlock new operating windows(Figures 1b and 1c)[8].

Dr Jonathan McDonoughis an early career researcher at Newcastle University who has significant interest and expertise in the areas of reaction engineering, fluid mechanics, flow chemistry, fluidization, heat transfer and 3D printing. Since completing his PhD in January 2018, Jonathan has already been the lead author on 8 publications, with further publications under review/development. One of Jonathan’s research themes is to exploit additive manufacturing for the fabrication of new and novel reactor geometries that can unlock previously unobtainable operating windows, paving the way for potentially new chemistries and processes. To this end, Jonathan is actively involved in several complementary projects that explore different aspects of this goal. This means he is now well-equipped to provide a perspective on the potential roles that additive manufacturing will play for the production of new intensified processes now and in the future.
