Abstract
A series of experiments of pool boiling with water, R141b, water/lithium chloride solutions were performed on a horizontal transparent heater (FTO) at Atmospheric pressure. The bubble behavior was observed from behind the heating surface with a high speed digital camera. The process of bubble growth can be divided into two areas by the behavior of adsorbed film. The difference of the process of bubble growth in two areas was attributed to bubble structure near the three phase contact line. Furthermore, instability of vapor/liquid interface, thermocapollary flow and marangoni flow generated in the three phase contact line were observed. It was considered that the bubble structure near the three phase contact line influenced causes of generating these phenomenon.
