文摘

Heat transfer over a superhydrophobic surface is analyzed by varying feature width. Nusselt number is a strong function of relative feature width. Role of secondary flow in turbulent heat transfer is analyzed. Turbulent Prandtl number for flow over superhydrophobic surfaces is presented. Substantial decrease in temperature fluctuations and thermal fluxes are observed.
