摘要：

This paper reports a numerical investigation of heat transfer decay characteristics in a plate channel with delta winglet vortex generator (DWVG) under the turbulent. The angle of attack of DWVG are investigated. Effects of geometry of vortex generator on heat transfer decay characteristics downstream of DWVG were carried out computationally at different Reynolds numbers. It was found that the Nusselt number increase with the increasing attack angle of the DWVG. The longitudinal vortex can transmit a long distance and decay continuously along the main stream, the longitudinal distance between the vortex generators is smaller than that of the distance of longitudinal vortex decay in order to ensure that the longitudinal vortex has a certain strength.
