【Abstract】 Various methods for achieving dropwise condensation were reviewed from the point of view of surface science. A new method for obtaining drop-wise condensation was presented. The concept of this new method was further confirmed through systematically experimental studies.The surfaces of stainless steel and copper tubes employed for dropwise condensation studies were treated with various surface techniques. Steam condensation under atmospheric pressure was carried out on these surfaces and steady duopwise condensation was observed. Experimental results and photographs of dropwise condensation were presented. The characteristics of dropwise condensation formed on specially treated surfaces was investigated and discussed.更多还原
