An Experimental Investigation of the Heat Transfer Characteristics of a Heated Cylinder Placed in a Cross Flow of Air.

摘要

Local heat transfer and pressure coefficients around a right circular cylinder were experimentally determined at Reynolds numbers ranging from 57,000to 495,000. The turbulence intensity of the free stream was approximately 0.5%. The cylinder was heated externally with a constant heat flux and simultaneously cooled in a cross flow of air. The steady state surface temperature increase above the air temperature was indicated by thermocouple information. Employing Newton's law of cooling,heat transfer coefficients were determined as a function of the angular location from the forward stagnation line. A comparison is made between the heat transfer and pressure data collected. (Modified author abstract)
