Simultaneous Measurement of Velocity and Heat Transfer in Unsteady Flow and Thermal Fields near the Wall Region (original) (raw)

Abstract

In this study, the correspondence relationship between the instantaneous heat transfer and flow behaviours downstream of a backward facing step is presented. The temporal sequence of the instantaneous flow and temperature distributions were simultaneously measured by using stereoscopic PIV system (2D-3C) and a high-speed infrared thermography. Using this system, the unsteady flow and heat transfer behaviours were investigated at Reynolds number of 2.5 × 10 3 in the xy cross section. The flow in the heated wall direction corresponded to the enhancement of the heat transfer spatially near the wall.
