... unexplored. In this study, a two-phase flow distribution model is used to investigate the impact of uneven heating on the flow distribution behavior of parallel microchannels undergoing boiling. Under lateral uneven heating (i.e., the channels are each heated to different levels, but the power input...

... when superheated. Normally the pressure gradient for two-phase flow is lower than that of vapor-phase flow at low quality region but is much larger at high quality region. Hence, the effective pressure gradient of the whole quality range may be a slightly higher than that of the single-phase (vapor...
