Book Description
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.

Book Description
Part I: Hot wire anemometry has been employed to determine certain characteristics of the turbulence in the free-stream of a low-speed, low-turbulence wind tunnel and to study the influence on such turbulence upon the fluctuations within a flat-plate boundary layer. A technique was employed which provided information concerning the propagation speed of the disturbances and this was used as a means of classification as to type or cause. It was found that Tollmien-Schlichting waves did not possess significant energy until a Reynolds number considerably higher than that of the theoretical neutral point was attained and that the subsequent growth exceeded the prediction of linear analysis. Part II: Distributed roughness present upon an aerodynamic surface alters the laminar boundary layer mean velocity profile such as to increase the instability presented here of the profile distortion for the case of small roughness in a Blasius boundary layer. The roughnesses tested include a single protuberance at Reynolds numbers below 50, the interaction between two such elements, the interaction between one element and a multitude of others, and the distortion due to distributed roughness.

Book Description
Experiments have been conducted on the interaction of strong sound fields with freq convection boundary layers on horizontal heated cylinders of 0.750-inch diameter. The interaction effects were observed through the measurements of total heat transfer from the cylinders to air under the influence of different types of sound environments. Three different types of sound fields were employed for the experiments: (1) standing plane waves generated by loud-speakers in an anechoic chamber; (2) Traveling plane wave fields generated by a mechanical siren in an anechoic duct; (3) Constant pressure or diffuse sound fields generated by a mechanical siren in a reverberant chamber. In all cases the generated sound was monochromatic ...
