Title Of Article :
Numerical Investigation of Heat Transfer on the Surface of a Circular Cylinder in Cross-Flow
Abstract :
In the present study, numerical analysis of heat transfer from heated cylinder, located in rectangular channel normal to the flow direction is studied. Finite volume based ANSYS-FLUENT 14 code is used in the solution of governing equations. Three different turbulence models as Std. k-ε, RNG k-ε and Realizable k-ε are used in computations for four different Reynolds numbers, Re= 4000, 8000, 16000, and 32000. It is found that numerical results obtained with Std. and RNG k-ε turbulence models are in good agreement with experimental data for maximum value of local Nusselt number on the cylinder. As expected that local Nusselt numbers increase with increasing Reynolds number for almost all points on cylinder.
