| Popis: | In the present study, numerical analysis of heat transfer from heated cylinder, located inrectangular channel normal to the flow direction is studied. Finite volume based ANSYS-FLUENT 14 codeis used in the solution of governing equations. Three different turbulence models as Std. k-ε, RNG k-ε andRealizable k-ε are used in computations for four different Reynolds numbers, Re= 4000, 8000, 16000, and32000. It is found that numerical results obtained with Std. and RNG k-ε turbulence models are in goodagreement with experimental data for maximum value of local Nusselt number on the cylinder. As expectedthat local Nusselt numbers increase with increasing Reynolds number for almost all points on cylinder. |
