Book Description
Numerical simulation on the influence of surface convection on the laminar air flow induced by natural convection in vertical parallel plates is explained. This simulation discussed symmetrically and asymmetrically for uniform heated flux (UHF) and uniform wall temperature (UWT) cases. The effects of variable fluid parameters taken into account for incompressible Navier-Stokes equations. The thermophysical properties variation are determined from air temperature at the inlet of channel. Distribution of several parameters in different sections considered and visited for natural convection. Many tests in various conditions have been undertaken for incompressible Navier-Stokes equations to allow evaluating average Nusselt numbers and air mass flow rate in this thesis. It has found out narrow vertical channels with different aspect ratios exhibit different heat transfer behaviours. Influence of mesh refinement on physical characteristic behaviour has been investigated. Several specific numerical codes, based on stabilized finite element method (FEM) used to solve the incompressible Navier-Stokes equations within the air gap region. These specific codes are suitable to determine the accuracy of heat transfer behaviours in different areas.

Book Description
Focusing on heat transfer in porous media, this book covers recent advances in nano and macro’ scales. Apart from introducing heat flux bifurcation and splitting within porous media, it highlights two-phase flow, nanofluids, wicking, and convection in bi-disperse porous media. New methods in modeling heat and transport in porous media, such as pore-scale analysis and Lattice–Boltzmann methods, are introduced. The book covers related engineering applications, such as enhanced geothermal systems, porous burners, solar systems, transpiration cooling in aerospace, heat transfer enhancement and electronic cooling, drying and soil evaporation, foam heat exchangers, and polymer-electrolyte fuel cells.

Book Description
A direct numerical simulation of a fully developed turbulent channel flow with passive heat transfer is performed. The time-dependent three-dimensional Navier-Stokes equations and advection-diffusion equation are solved numerically using a pseudospectral technique with 1,064,960 grid points in physical space (128 x 65 x 128 in x, y, z). No subgrid scale model is employed since all essential turbulence scales are resolved. The Reynolds number is 2262, based on the half channel height and bulk velocity, and the Prandtl number is 1. The Nusselt number is predicted to be 25.36. A large number of one-point turbulence statistics are computed and compared with existing experimental data taken at similar Reynolds and Nusselt numbers. Agreement with the existing experimental data is excellent except for some discrepancies in the near wall region, y$sp+$ $

Book Description
Natural convection is a phenomenon occurs when heat is transferred to a fluid, which raises its temperature and decreases its density and consequently makes it flows upward. This book is a complete tutorial on how to simulate this kind of phenomenon using ANSYS Fluent 19.2. This is applied to a simple application of cooling a small surface using a heat sink. The tutorial starts with creating the 3D domain itself inside ANSYS DesignModeler, then discretizing it (Meshing) in ANSYS Meshing application. After that, the model is defined in Fluent with the appropriate boundary conditions. Finally, the output data is processed in Fluent to see the resulting flow around the heat sink and the temperature distribution in both the fluid and the heat sink itself.This a tutorial for the complete steps required to complete this kind of simulation. It is presented in the form of high-resolution screenshots of the applications' windows which are preceded by a textual description of the steps. Also, some of these screenshots are followed by an explanation of the different choices when seen appropriate.

Book Description
Der Band enthält den Abschlußbericht des DFG-Schwerpunktprogramms "Flußsimulation mit Höchstleistungsrechnern". Es führt die Arbeiten fort, die schon als Band 38 in der Reihe "Notes on Numerical Fluid Mechanics" erschienen sind.Work is reported, which was sponsored by the Deutsche Forschungsgemeinschaft from 1993 to 1995. Scientists from numerical mathematics, fluid mechanics, aerodynamics, and turbomachinery present their work on flow simulation with massively parallel systems, on the direct and large-eddy simulation of turbulence, and on mathematical foundations, general solution techniques and applications. Results are reported from benchmark computations of laminar flow around a cylinder, in which seventeen groups participated.
