Abstract
The behavior of the turbulent fluid flow after an obstacle is difficult to accurately predict via analytical relations. This difficulty is further increased when the obstacle impeding the flow is heated. To gain a further understanding of heat transfer in a turbulent flow, an ANSYS Fluent simulation using the Shear-Stress Transport (SST), Large Eddy Simulation (LES), and Improved Delayed Detached Eddy Simulation (IDDES) turbulence models was created using two different computational meshes. This simulation mimicked an experiment completed by Antonia and Browne in their paper, “Heat transport in a turbulent plane wake,” [1]. The different models were then compared to each other, finding SST the most accurate with LES the least so in these preliminary results.
