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...
