Microchannel two-phase flow of refrigerant R1234ze.
Two-phase slug flow in square cross-section microchannels. 3D Finite Element simulation was successfully carried out to predict bubble shape, velocity, liquid slug and liquid film thickness in the scope of the CMOSAIC project financed by NanoTera in Switzerland. The liquid and gas phases correspond to the refrigerant R 1234ze and the channel width is 100^-6m.
