“…In addition, the flow and heat transfer are transient, laminar and two-dimensional. The governing conservation equations for the fluid and porous layers and also for the solid shell have been formulated in dimensionless form using stream function, vorticity and temperature variables [7], [8]:  for the pure fluid layer:…”

“…1-Eq. 6 with corresponding initial and boundary conditions were solved by finite difference method [7], [8], [24], [25] using the uniform grid. For an approximation of the convective terms we used the monotonic Samarskii scheme of the second order, allowing considering a sign of velocity and for an approximation of the diffusion terms we used the central differences.…”

“…One of the advantages of Darcy-Brinkman model is that the dynamic viscosities is taken the same in both layers (μ eff = μ f ) [25]. Hence, the porous-fluid interface conditions can be written as; (10a) where is the thermal conductivity ratio.…”
