Thermal Transport Due to Liquid Jet Impingement on Superhydrophobic Surfaces with Isotropic Slip: Experimental Validation

Orbital ATK Conference Center

This paper presents an experimental analysis of thermal transport due to jet impingement at isotropic superhydrophobic surfaces. Agreement with an analytical model over a range of Reynolds numbers varying from 1x10^4 to 2.5x10^4 and surface heat fluxes from 2.5x10^4 to 4.9x10^4 W/m^2 is considered. Excellent agreement between the model and the experiments are demonstrated for smooth hydrophobic surface. Preliminary agreement is demonstrated between the model and the results at a post patterned superhydrophobic surface.
