| چکیده فارسی مقاله |
The Lattice Boltzmann method (LBM) is employed to simulate heat transfer in flow past three arrangements of and horizontal and vertical rectangular چکیده obstacle under isothermal boundary condition. A thermal lattice Boltzmann BGK model is purposed to simulate the two dimensional forced convection for the governing parameters as Reynolds number, Re=100 and the Prandtl Number for laminar flow 𝑃𝑟=0.71. Pressure distributions, isotherms and streamlines were obtained. Vortex shedding maps are observed in detail for various cases and signified that lattice Boltzmann method can be effectively used to capture velocity fluctuations. The present results are in good agreement with existing experimental and numerical data. |
