Dropwise condensation process consist of several discontinuously and irregular process. Therefore, it is difficult for dropwise condensation to analysis of continuously and regular methods as filmwise condensation and another heat transfer phenomenon. It is widely thought that drop growing speed and drop size distribution is paramount importance for construction of dropwise condensation theory. In addition, it is well known that the presence of non-condensable gas is reduced the heat transfer coefficient. However the research of drop growing speed and condensation cycle is not performed a lot. The objective of this study is to measure the drop growing speed and the condensation cycle in the presence of non-condensable gas, and visualization of dropwise condensation process is performed using a digital video camera. In the result of visualization method, it is understandable that the causes with decreases of heat transfer coefficient and amount of heat transfer in the reduction of drop glowing speed.
