Large Eddy Simulation of Turbulent Heat Transfer in a Channel with a Rectangular Cylinder

초록

Periodic vortex shedding from a cylindrical object immersed in cross-flow has been one of the classical research subjects for decades, because it induces periodic force loading on the object, which could significantly damage the cylindrical structure. Thus most of research on the vortex shedding has been focused on how to control it in order to minimize its damage. On the other hand, the large-scale vortices shed from a cylindrical object as a vortex generator can be used to enhance heat transfer in a heat exchanger. In this study, Large-Eddy Simulation of turbulent heat transfer in a channel with a rectangular cylinder(Fig. 1) at Re
