Computation of conjugate heat transfer over a 2d circular cylinder in a low speed crossflow by a ghost cell immersed boundary method

Abstract

A ghost cell immersed boundary method is employed to compute the conjugate heat transfer over a circular cylinder in crossflow. The cylinder is internally heated by a circular surface of constant temperature. The conjugate heat transfer boundary treatment proposed at fluid-solid interface is shown to yield second order accurate solution. To demonstrate the capability of the current method, the location of the internal heating surface is varied to examine its effect on the heat transfer.
