Heat transfer and pressure characteristics of two-dimension offset jet of fully developed flow were investigated experimentally. Flow visualization for the same flows was carried out using the high speed camera. The Reynolds number Re was changed in 1.5 X 103 to 7.0 X 103, and the offset ratio H/h was changed in 0.5, 1.0 and 1.5. The result shows that rolling up vortices appear downstream of the reattachment point. Two peaks exist at the Nusselt number distribution of the laminar flows with H/h=0.5 and 1.0. The 1st peak appears near the reattachment point of a jet flow, and 2nd peak appears in the neighborhood which vortices eject from the wall.
