Use of heat flux sensors in investigations of local heat transfer in pipes
Abstract
Local heat transfer in the flow of air in a circular pipe 36 mm in diameter and 2000 mm in length was measured with single heat flux sensors and with a battery of such sensors. Data reveal an intensity of local heat transfer in the region of developed flow at Reynolds numbers in the range 10,000-120,000, length-to-diameter ratios above 50, under conditions of complete heating of the pipe in agreement with the calculations of Legkii and Koval' (1974) and Isanchenko et al. (1969).
