The effects of a longitudinal vortex on the local heat transfer and time-spatial temperature distributions downstream of backward-facing step were investigated. The longitudinal vortex was generated by the pairs vortex generators consisting of two rectangular blades, increasing linearly in separation downstream, are aligned laterally to the flow with a spacing at upstream region of the step. The temperature at near the reattachment point is fluctuated periodically for vortex generator, and the distribution of heat transfer coefficients averaged spanwise direction becomes flatter than that of the smooth. However, characteristics of heat transfer is similar to the smooth.
