Abstract: This paper reports the computational fluid dynamics (CFD) modelling of heat transfer analysis from a heated target surface, using single swirling jet air impingement at different Reynolds numbers. Swirl is produced by using a nozzle body with half-length downstream twisted tape insert (HLDI). The nozzle to plate (target surface) distance and twist ratio (y) of twisted tape is taken to be constant as 21mm (H/D = 1) and y = 2.93 respectively. Different Reynolds numbers as 12000, 17000, 22000 and 27000 are used to investigate the heat transfer characteristics on heated surface.
