Abstract:
In this thesis, the effects of conduction on mixed convection flow in a vented
rectangular cavity and the effect ofconvectiort on magnetohydrodynarriic (MHD)
have been investigated numerically. The development mathematical models of the
physical problems are governed by the coupled equations of continuity, momentum
and energy along with the corresponding boundary conditions. Using a class of
appropriate transformationS, the governing equations along with the initial and
boundary conditions are transformed into non-dimensional form, which are then
solved by employing a finite-element scheme based on the Galerkin method of
weighted residuals. Comparisons with previously reported investigations are
performed and the results show very good agreement. In the present study, the
obtained results are, presented in terms of streamlines, isotherms, average Nusselt
number and average bulk temperature for various relevant dimensionless groups. The
obtairied results reveal that both the flow and thermal fields inside the cavity strongly
depend on the relevant dimensionless groups.
