Geometry and orientation effects in non-uniformly heated microchannel heat exchangers using supercritical carbon dioxide

Creator:

Jajja, Saad A., Sequeira, Jessa M., and Fronk, Brian M.

Abstract:

There is growing interest to use supercritical carbon dioxide (sCO2) as a working fluid in thermal management applications. This study investigates the thermal-hydraulic performance of microchannel heat sinks as a function of flow channel geometry and orientation at operating conditions representative of electronics cooling applications. Three different experimental test sections,...

Experimental investigation of supercritical carbon dioxide in horizontal microchannels with non-uniform heat flux boundary conditions

Creator:

Jajja, Saad A., Zada, Kyle R., and Fronk, Brian M.

Abstract:

Supercritical carbon dioxide (sCO2) experiences a drastic change in its thermophysical properties near the thermodynamic critical point. A non-linear thermophysical property variation can influence the heat transfer behavior of sCO2 which is not predicted well by conventional single phase heat transfer theory. This can become a major hindrance in the...
