Abstract

Thermo images and heat transfer characteristics downstream of a backward-facing step were measured varying separation distances between pairs vortex generators which were set upstream of an entrance of step in order to control the heat transfer. The pair of vortex generators is made of two rectangular blades widening downstream. Addition of the longitudinal vortex which is produced by the vortex generators to the main shear layer flow separated from step entrance caused the reattachment point of main flow to move upstream, suppressed the fluctuation of reattachment flow, and the heat transfer consequently was improved in the recirculation region.
