Abstract

Convective heat transfer coefficient and its interdependency with various key parameters are analyzed. Air is used as the working fluid impinging on the flat surface. A thorough investigation of velocity and temperature distributions was performed by varying Nozzle Velocity and Height over Diameter ratio (H/D). Nusselt number and Turbulent Energy are presented for the impingement surface. It was found that for H/D ratios ranging between 6 and 8, nozzle velocities over 20 m/s provide a large percentage increase in heat transfer.
