Isochoric Heat Exchanger
Research Activity
Isochoric Heat Exchanger.
“Stirling” like thermodynamic cycle plants require a countercurrent heat exchanger operating under isochoric (constant volume) conditions. Our team is developing the Isochoric, Countercurrent Heat Exchanger (ICHE) concept which employs two traveling cavity cascades, moving in opposite directions. Heat flows through the separating plate, which creates a lid driven cavity cascade on each side. So far the activity has concentrated on two aspects :( 1) the integration of an experimental facility that will provide data for various cavity configurations (the facility is completed). (2) The analytical study of the influence of various transient mechanisms on the heat transfer and temperature distribution on the separating plate against the plate thickness.
