Flow Boiling and Flow Condensation

flow boiling in a channel

Developments in many modern applications are encountering rapid escalation in heat dissipation, coupled with a need to decrease the size of thermal management hardware. These developments have spurred unprecedented interest in replacing single-phase hardware with boiling and condensation counterparts.

We are interested in understanding the fundamental phenomena encountered during these two-phase flow scenarios. We study flow behaviors encountered in both small scale micro-channels and large-scale macro-channels encountered across many applications in nuclear, aerospace, defense and automotive industries. In our lab, experiments are conducted on a full scale two-phase flow conditioning loop that can do both boiling and condensation testing. The facility is also equipped with advanced diagnostic tools with high speed imaging capability to capture the two-phase interfacial behavior and particle image velocimetry capability to capture the local fluid phase velocities.
