This book was released on 1960 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 ...
