Abstract : The program of work was directed to the study of the effects of free-stream turbulence and of flow oscillations on the shearing stresses and heat transfer from immersed bodies to fluid streams, and to the study of local effects of intense sound fields on flow and heat transfer. Analytical and experimental investigations of the effects of free-stream turbulence on flow and heat transfer were performed for forward stagnation regions (on both a flat plate and a cylinder), and for a flat plate with a rounded leading edge in zero and favorable pressure gradients. Experiments and analysis for effects of sound on natural convection gave closely corresponding values for local heat transfer rates. A resonant interaction of sound with separated shear layers was investigated experimentally. (Author)
