Experiments were performed on the convective boiling in Horizontal minichannel with R-290 and R600a. The test section was made of stainless steel tube with inner diameter of 3 mm, length of 1000 mm and it is uniformly heated along the tube with heat flux was varied from 5 kW/m2 up to 8 kW/m2. From the experiments, taken data was results the temperature of test section inner diameter and Reynolds Number of liquid phase and gas phase. The Reynolds Number represent flow of the two phases in test section. Comparison of Reynolds Number from the two refrigerant shows that Isobutana have better value than Propana since its Reynolds Numbers is lower than Propana in similar mass flux and heat flux condition. Based on the Reynolds Number, Chisolm Number will concluded to determine two phase friction multiplayer., This study discusses the Reynolds Number of two phase flow in Horizontal Mini Channel.
