A Turbulence Model for the Heat Transfer Near Stagnation Point of a Circular Cylinder

Research output: Contribution to journal › Article › peer-review

Abstract

A one-equation low-Reynolds number turbulence model has been applied successfully to the flow and heat transfer over a circular cylinder in turbulent cross flow. The turbulence length-scale was found to be equal 3.7 y up to a distance 0.05δ and then constant equal to 0.185δ up to the edge of the boundary layer (where y is the distance from the surface and δ is the boundary layer thickness).

The model predictions for heat transfer coefficient, skin friction factor, velocity and kinetic energy profiles were in good agreement with the data. The model was applied for Re ≤250,000 and Tu _∞ ≤0.07.
