The investigation presented a numerical simulation on heat transfer behaviors in microchannel evaporator of a CO air conditioning system. The conditions for numerical simulation were applied by the experimental data of a CO 2 air conditioning cycle. This cycle worked with the cooler pressure of 85 bar, evaporator pressure of 37 bar, and the CO 2 flow rate of 5.2 g/s. The temperature and pressure in microchannels are uniform; they are suitable...

In this paper, the effects of mass flow rate on heat transfer behaviours for two phase flow in rectangular microchannels were investigated by numerical simulation and experiments. The optimal approach for searching the best value of mass flow rate was studied. It was indicated that the rectangular microchannel heat sink with the mass flow rate of G = 0.4 g/s is the best choice for designing (Based on the fixed parameters as mentioned above)...
