Current Research

I am currently involved in an EU project TriSOFC, which involves the development of a novel single component solid oxide fuel cell that uses the waste heat for heating and cooling. The work involves modelling, simulation, experimental work and field trials.

I am also involved in the modelling and experimental investigation of a hybrid vapour-compression/jet-pump refrigeration system for the transport sector. We will be using carbon dioxide as the refrigerant in the vapour-compression system and a natural refrigerant such as water or ethanol in the jet-pump system. The jet-pump system will be driven by waste heat from the exhaust gases of an internal combustion engine.

Past Research

I recently concluded a research project involving a theoretical and experimental investigation of an indirect evaporative cooling system integrated with a wind driven natural ventilation system.

I developed a variable buoyancy system for underwater vehicles at the University of Aberdeen. The system used a small hydraulic circuit and a pressure intensifier housed in a water tight enclosure to fill and empty a buoyancy tank. The system was capable of operating at full ocean depth (6000m). A second system was developed for operation at shallow depths (<300m).

Future Research

I am interested in thermoelectric refrigeration systems and have been investigating electrically conductive polymers that might be useful in such devices. I am also interested in biomimetics and am researching thermoelectric mechanisms in nature.
