Condensation coefficients were obtained experimentally through dropwise condensation on the silicon surface with hydrophobic coating. The experiments were conducted in a vacuum chamber at low pressure around 3kPa in order to reduce the accumulation of non-condensable on the liquid-vapor interface. Experimental results of heat transfer coefficient show good agreements with previous studies. Also, the condensation coefficients were estimated in the range of 0.2-1.0 if we consider the constriction resistance of dropwise condensation.
