INVESTIGATION OF THE HEAT TRANSFER CHARACTERISTICS OF A TWO-DIMENSIONAL JET IMPINGING ON A SEMI-CYLINDER.

Abstract

Boundary layer methods are used to find the heat transfer rate caused by a two-dimensional jet impinging on the inside surface of a semi-cylinder. Because of a wider pressure distribution on the semi-cylinder, the solution predicts a delayed transition from a laminar to a turbulent boundary layer. This delayed transition causes the average heat transfer from the semi-cylinder to be less than the average heat transfer from the flat plate. Experimental data support the theoretically predicted heat transfer rate from the stagnation area of the semi-cylindrical plate and indicate heat transfer rates that are less than those predicted by theory in the other regions of the flow field.
