Özet:

 

In the present paper, numerical simulation is carried out to investigate turbulent flow structure and heat transfer analysis in a two-dimensional horizontal plane channel, contains square blocks arranged in tandem or side by side arrangement. The k-ε model is used to describe turbulence phenomena, and governing equations are solved by a finite volume method, with SIMPLEC algorithm is applied for the coupling of the velocity-pressure variables. The power-law scheme is used for the discretization of the convective terms in the momentum equations. Presented results illustrates the effect of the transverse (GT) and longitudinal (GL) spacing between the blocks on flow structure and heat transfer for a wide range of Reynolds number (104≤ Re ≤5×104). Numerical results show a very good agreement in comparison with available data in the literature.
