EXPERIMENTAL HEAT TRANSFER AND TEMPERATURE DISTRIBUTION IN A HOLLOW TUBE WITH INTERNAL AIRFLOW AT HIGH TEMPERATURE AND PRESSURE

Abstract

Results are presented of heat transfer tests conducted on a thick-walled, stainless steel tube subjected to an internal subsonic flow of air at pressures up to 465 psia and temperatures up to 1850 R. A total of six test runs were conducted at Reynolds Numbers (based on the diameter) which ranged from 4 x 10 to the 5th to 2 x 10 to the 6th power. The heat transfer data were in excellent agreement with a semi-empirical relation. The transient temperature distribution through the tube thickness was calculated for two cases from the transient, one-dimensional, cylindrical heat conduction equation using the theoretically determined heat transfer coefficients. A comparison of the temperature distribution obtained in this manner with experimentally measured temperatures under the same stagnation conditions showed fair agreement. (Author)
