Abstract

Experimental investigations of flow pulsation effects on forced convection heat transfer were carried out using a test section of SS304 tube with 1. 092cm ID. Flow pulsations were produced by an oscillator consisting of a motor-driven ball valve system. The period of pulsation ranged from 2. 6 to 13. 5 seconds and Reynolds number from 3400 to 27000. It was found that in the range of the experiment, the heat transfer coefficients with pulsation are reduced and the magnitude of reduction mainly depends on amplitude.
