A temperature correlation for the radiation resistance of a thick-walled circular duct exhausting a hot gas. Journal of the Acoustical Society of America, 75(1), 63-71. doi: 10.1121/1.3903010001-4966http://hdl.handle.net/10919/52650It is often useful to know the radiation impedance of an unflanged but thick-walled circular duct exhausting a hot gas into relatively cold surroundings. The reactive component is shown to be insensitive to temperature, but the resistive component is shown to be temperature dependent. A temperature correlation is developed permitting prediction of the radiation resistance from a knowledge of the temperature difference between the ambient air and the gas flowing from the duct, and a physical basis for this correlation is presented.9 pagesapplication/pdfen-USIn CopyrightTemperatureRadiation impedanceAcoustic pressureArticle - Refereedhttp://scitation.aip.org/content/asa/journal/jasa/75/1/10.1121/1.390301https://doi.org/10.1121/1.390301
