Book Description
Finite Element Simulation of two-dimensional laminar steady state natural convection in a rectangular open cavity has been studied. A heated circular cylinder is placed at the centre of the cavity where the left sidewall to the cavity is heated by a constant heat flux. The top wall is kept cool and the bottom wall is kept at a hot temperature. The fluid is concerned with different Prandtl numbers. The properties of the fluid are assumed to be constant. The physical problems are represented mathematically by different sets of governing equations along with the corresponding boundary conditions. In this study, finite element method for steady state incompressible natural convection flows is used to find the numerical results. The Galerkin Weighted Residual method of finite element formulation is applied to discretize the non-dimensional governing equations. The results of the investigation are obtained in terms of streamlines, isotherms and heat transfer characteristics Nusselt numbers for different Grashof numbers and different inclination angles of the cavity ranges from 0o to 45o.

Book Description
Natural convection in a side or differentially heated cavity is a classical problem in heat transfer. The problem represents a wide range of engineering applications and has also been commonly used as a benchmark problem for validating Computational Fluid Dynamics (CFD) computer programs. This study investigates turbulent natural convection of a fluid with a Prandtl number of 0.71 in a differentially heated square cavity with adiabatic top and bottom walls. Two different boundary conditions are applied to the side walls; (1) the standard isothermal side wall problem, and (2) the mixed isoflux/isothermal problem, which has a constant heat flux on the heated side wall with an isothermal cold wall on the opposite side. An experimental study is carried out to determine the net convective heat transfer between isothermal hot and cold walls for a range of wall temperature differences in the laminar flow regime. The experiment data is compared with CFD predictions, and they are found to be in reasonable agreement......

Book Description
In this book we have tried to provide a user-friendly introduction to the topic of convection in porous media. We have assumed that the reader is conversant with the basic elements of fluid mechanics and heat transfer, but otherwise the book is self-contained. Only routine classical mathematics is employed. We hope that the book will be useful both as a review (for reference) and as a tutorial work (suitable as a textbook in a graduate course or seminar). This book brings into perspective the voluminous research that has been performed during the last two decades. The field has recently exploded because of worldwide concern with issues such as energy self-sufficiency and pollution of the environment. Areas of application include the insulation of buildings and equipment, energy storage and recovery, geothermal reservoirs, nuclear waste disposal, chemical reactor engineering, and the storage of heat-generating materials such as grain and coal. Geophysical applications range from the flow of groundwater around hot intrusions to the stability of snow against avalanches.
