Flow Boiling in Minichannels

 Flow boiling in minichannels

Two phase heat transfer in small channels has many practical applications like, miniature heat exchangers, high powered electronics, miniature refrigeration system. Flow boiling in these compact channels offers many potential advantages like, cope with high heat flux, less fluid inventory, compactness in size.

Test apparatus is a closed loop with heating and cooling provisions. Test set up is designed in a way to carryout heat transfer, pressure drop and visualization studies simultaneously. Furthermore different orientations (vertical, horizontal) for the test section are also possible.

Main objectives with this project are, to investigate the dominant mechanisms (to reveal the hidden physics) and to suggest reliable prediction methods.
