Numerical investigation of flow boiling in double-layer microchannel heat sink
Double-layer microchannel heat sinks (DL-MCHS) are considered as an effective solution of temperature non-uniformity on the surface of microelectronic devices. However, only single-phase flow is analyzed so far in DL-MCHS. In this paper, numerical investigation has been carried out to observe the...

| description | Double-layer microchannel heat sinks (DL-MCHS) are considered as an effective
solution of temperature non-uniformity on the surface of microelectronic devices.
However, only single-phase flow is analyzed so far in DL-MCHS. In this paper,
numerical investigation has been carried out to observe the flow boiling phenomena in
DL-MCHS. FLUENT ver. 14.5 has been used to simulate the multiphase flow in this particular heat sink. A mathematical model of the system has been provided. From the results, it is observed that two-phase heat transfer coefficient increases with increasing heat flux and decreases after achieving critical heat flux (CHF). For the considered channel, CHF is found to be550×〖10〗^4 Wm^(-2).Highest heat transfer rate during boiling is 6.4 W. |
