Research activities of our laboratory can be broadly classified into two categories: heat transfer and solid sorption storage/ cooling.
Heat transfer research aims at miniaturisation of heat exchangers. Miniaturised, cryo-compatible heat exchangers offer challenges to achieve high efficiency with reduced heat ingress, axial heat conduction, pressure drop and preferably at low cost. The first prototype unit has been built and tested.
Heat transfer research, in our laboratory, also envisages using metal foam as extended heat transfer surfaces or fins owing to their high heat transfer surface area density, open porosity, interconnectivity and ability of creating eddies. Metal foam has been found extremely effective as passive radiation coolers in space cryogenics (cooling accomplished by radiating heat to outer space). Both experimental and theoretical research is progressing simultaneously in this field. Other effective utilisation of open porous metal foam is also in progress.
Solid sorption research has spread in two directions. Cryosorption storage of gaseous hydrogen in carbonaceous materials is the area in which the research is currently limited to theoretical level.
The other aspect of sorption research is related to cooling. Aiming at an effective utilisation of large heat of desorption, the present research is focussed on overcoming the limitations typically linked to solid sorption processes. Usually, intermittency in solid sorption cooling is avoided with the use of multiple adsorbent beds triggering operational complexities. Development of continuous solid sorption cooling in a single adsorbent tube, with the rapid pressurisation and depressurisation, can substantially reduce this problem. Active research is being pursued for couple of years.
