Thermal Convection in a Heated-Block Duct with Periodic Boundary Conditions by Element-by-Element Treatment

نویسندگان

چکیده

The periodic nature of stream-wise flow occurs in a cooling channel so frequently due to the multiple heat sources electronic equipment, demanding creation an effective technique improve heat-cooling convection. This work explores thermal convection enhancement heated-block duct for boundary conditions using element-by-element (EBE) treatment semi-implicit projection finite element method (FEM) through preconditioned conjugate gradient (PCG) solver. effects changing Reynolds numbers (100, 175, and 250) on rectangular cylinders installed under were studied time-mean Nusselt number enhancement, friction factor performance coefficient. results show that above upstream block promote modifying no cylinders. However, increasing increases enhancement. As result, case with cylinder every two blocks has best

Approximate solution of laminar thermal boundary layer over a thin plate heated from below by convection

In this paper, an integration of a symbolic power series method - Padé approximation technique (PS - Padé), was utilized to solve a system of nonlinear differential equations arising from the similarity solution of laminar thermal boundary layer over a flat plate subjected to a convective surface boundary condition. As both boundary conditions tended to infinity, the combination of series solut...
