...Jaeseon Lee; Issam Mudawar This study examines the pressure drop characteristics of subcooled two-phase microchannel heat sinks. A new model is proposed, which depicts the subcooled flow as consisting of a homogeneous two-phase flow layer near the heated walls of the microchannel and a second...

Pfefferkorn This study concerns pressure drop of adiabatic water liquid-vapor two-phase flow across an array of 1950 staggered square micropin-fins having a 200 × 200 μ m cross section by 670 μ m height. The ratios of longitudinal pitch and transverse...

... 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...

In the present study, experiments were conducted with adiabatic nitrogen-water two-phase flow in a rectangular micro-channel having a 0.406 × 2.032 mm 2 cross-section. Superficial velocities of nitrogen and water ranged from 0.08 to 81.92 m/s...
