Gözenekli ortamlarda doğal taşınım ile ısı transferinin sayısal olarak incelenmesi

In this thesis, natural convective heat transfer through an impermeable and fluid saturated porous medium is investigated numerically. A FORTRAN based code is developed and used in order to present the outputs of the applied model and the assumptions. The solutions of flow fields and temperature fields are presented within the medium. Moreover, Nusselt number variations for different values of Darcy, Prandtl, and Rayleigh numbers, and some other thermodynamic properties are investigated and presented. Comparisons with previous studies are also presented. Finally, the transition from convection to conduction in the heat transfer regime inside the porous medium is examined and an equation for estimating the heat transfer inside the porous medium is presented.M.S. - Master of Scienc
