Thermal analysis of two-phase microchannel cooling

A design calculation has been performed to determine thermal limits in support of an experiment in two-phase microchannel water cooling. Under the operating condition (one atmosphere pressure and 23{degrees}C inlet temperature), the calculation predicts that the experimental channel can withstand a maximum surface temperature of 115{degrees}C and a heat flux up to 975 W/cm{sup 2} without exceeding the critical heat flux limit. The predicted results also indicate that a uniform heat flux along the channel in the two-phase domain can be achieved so that the heat losses from the experimental test section can be calculated in a straightforward manner.
