Boiling heat transfer in vertical rectangular mini-channels with a width of 2 mm and a length of 390 mm is studied in this paper. The courses of bubbles generation, growth and departure were numerically simulated, the influence of the wall overheating and the movement of bubble bottom micro-layer is analyzed and compared with the experimental datum. All the calculation conducted takes the gravity, surface tension and wall adhesion into account. It is found that surface tension is much more important than gravity in the process of boiling heat transfer. As the overheating is increased, the departure diameter D of bubbles increases significantly. When the bubble diameter D is larger than 1.5 mm, it will be influenced by the incoming flow. The existence of bubble bottom micro-layer accelerates the flow convection on the wall and increases the coefficient of heat transfer. The results of simulation have a good coherence with experimental datum.
