چکیده
Numerical modeling of convection suitable for nite volume methods for steady-state, multidimensional, incompressible, turbulent ows is considered. Two methods used to achieve higher order accurate and oscillation-free solutions are discussed, namely ux limiting and variable normalization. A uniied formulation, which brings together most existing higher order monotonicity preserving schemes, is discussed. The uniied formulation allows the inclusion of higher order non-monotone schemes, and a new class of ux limiters is presented. Some numerical results are shown for two-dimensional ows, and the superiority of the ux-limiting schemes is connrmed by comparison with results of the rst order upwind scheme.

Meshless Local Petrov-Galerkin (MLPG) Method for Convection-Diffusion Problems
Due to the very general nature of the Meshless Local Petrov-Galerkin (MLPG) method, it is very easy and natural to introduce the upwinding concept (even in multidimensional cases) in the MLPG method, in order to deal with convection-dominated flows. In this paper, several upwinding schemes are proposed, and applied to solve steady convectiondiffusion problems, in one and two dimensions. Even fo...
متن کاملTransient Natural Convection Flow on an Isothermal Vertical Wall at High Prandtl Numbers: Second-Order Approximation
The method of matched asymptotic expansions, which has been used in previous studies of steady natural convection flow, is extended here to transient natural convection flow at high Prandtl number (Pr). Second-order expansion solutions, valid for large Prandtl numbers, are presented for the transient natural convection flow near a vertical surface which undergoes a step change in temperature. T...
متن کاملA new approach to enforcing discrete maximum principles in continuous Galerkin methods for convection-dominated transport equations
This paper presents a set of design principles and new algorithmic tools for enforcing maximum principles and/or positivity preservation in continuous finite element approximations to convection-dominated transport problems. Using a linear first-order advection equation as a model problem, we address the design of first-order artificial diffusion operators and their higherorder counterparts at ...
متن کاملMixed Upwinding Covolume Methods on Rectangular Grids for Convection-Diffusion Problems
We consider an upwinding covolume or control-volume method for a system of first order PDEs resulting from the mixed formulation of a convection-diffusion equation with a variable anisotropic diffusion tensor. The system can be used to model the steady state of the transport of a contaminant carried by a flow. We use the lowest order Raviart–Thomas space and show that the concentration and conc...

In this paper, an enhanced computational code was developed using finite-volume method for solving the incompressible natural convection flow within the cylindrical cavities. Grids were generated by an easy method with a view to computer program providing. An explicit integration algorithm was applied to find the steady state condition. Also instead of the conventional algorithms of SIMPLE, SIM...
