The effect of the thermal conductivities of condenser materials on dropwise condensation heat transfer has not been resolved yet. Numerical simulation of dropwise condensation heat transfer of steam on copper
stainless steel
zinc
mild steel surfaces are performed in this paper by using a model of dropwise condensation heat transfer proposed by the present authors. The results indicate that dropwise condensation heat transfer coefficient is greatly dependent upon the surface thermal conductivity
and decreases with decreasing surface thermal conductivity.
