TL;DR: From the analysis of a conjugate problem of convective heat transfer in a laminar incompressible flow around a flat plate of a finite thickness, the design formulas are suggested for a local Nusselt number Nux(Nux/Nux0)−1 = CBx, (0).

TL;DR: In this article, the Navier-Stokes equations are transformed into a system of equations with the stream function and the vorticity as the dependent variables, and the energy equation is solved over the entire domain, using corresponding properties for the solid and fluid regions.
Abstract: Mixed convection is studied numerically in the case of an isolated, constant source of heat input within a rectangular enclosure. An external flow enters the enclosure through an opening in the left vertical wall and exits from another opening in the right vertical wall. This configuration leads to a conjugate heat transfer problem and simulates the air cooling of electronic components. Various parameters arise in this problem, particularly the Reynolds number, the buoyancy parameter Gr/Re2, the ratio of the thermal conductivity of the wall material to that of the fluid taken as air, and several geometric parameters. The time-dependent continuity and Navier-Stokes equations are transformed into a system of equations with the stream function and the vorticity as the dependent variables. The energy equation is solved over the entire domain, using the corresponding properties for the solid and fluid regions. The control volume approach is employed in order to discredit the governing equations for their numer...

TL;DR: In this paper, the steady state heat transfer characteristics of a thin vertical strip with internal heat generation were studied and the non-dimensional temperature distribution in the strip was obtained as a function of the following parameters: (a) the intensity and distribution of the internal heat sources, (b) the aspect ratio of the strip, (c) the longitudinal heat conductance, and (d) the Prandtl number of the fluid.
