| Abstract: | Experiments were conducted to investigate flow boiling of working fluids with low boillug temperatures, such as methanol, flowing through rectangular microchannels. The results show some of the unique phenomena resulting from flow boiling inside microchannels. The wall temperature decreases significantly when the boiling begins and fluctuates as the heat flux increases. The flow boiling heat transfer rate is found to be a function of the microchannels structure and the thermal physical properties of the working fluid as related to the capillary effect. Further research is needed to establish the quantitative relationship. |
