Natural convection of air in a square cavity: A bench mark numerical solutionAbstract Details are given of the computational method used to obtain an accurate solution of the equations describing two‐dimensional natural convection in a square cavity with differentially heated side walls. Second‐order, central difference approximations were used. Mesh refnement and extrapolation led to solutions for 103 ⩽Ra⩽10 6<... ... hiện toàn bộ

Reproducing kernel particle methodsAbstract A new continuous reproducing kernel interpolation function which explores the attractive features of the flexible time‐frequency and space‐wave number localization of a window function is developed. This method is motivated by the theory of wavelets and also has the desirable attributes of the recently proposed smooth particle hydrodynamics (SPH) methods, m... ... hiện toàn bộ

High‐order CFD methods: current status and perspectiveSUMMARY After several years of planning, the 1st International Workshop on High‐Order CFD Methods was successfully held in Nashville, Tennessee, on January 7–8, 2012, just before the 50th Aerospace Sciences Meeting. The American Institute of Aeronautics and Astronautics, the Air Force Office of Scientific Research, and the German Aerospace Center provided much neede... ... hiện toàn bộ

Application of generalized differential quadrature to solve two‐dimensional incompressible Navier‐Stokes equationsAbstract A global method of generalized differential quadrature is applied to solve the two‐dimensional incompressible Navier‐Stokes equations in the vorticity‐stream‐function formulation. Numerical results for the flow past a circular cylinder were obtained using just a few grid points. A good agreement is found with the experimental data.

Curvature‐compensated convective transport: SMART, A new boundedness‐ preserving transport algorithmAbstract The paper describes a new approach to approximating the convection term found in typical steady‐state transport equations. A polynomial‐based discretization scheme is constructed around a technique called ‘curvature compensation’; the resultant curvature‐compensated convective transport approximation is essentially third‐order accurate in regions of the sol... ... hiện toàn bộ

Natural convection in a square cavity: A comparison exerciseAbstract A number of contributed solutions to the problem of laminar natural convection in a square cavity have been compared with what is regarded as a solution of high accuracy. The purposes of this exercise have been to confirm the accuracy of the bench mark solution and to provide a basis for the assessment of the various methods and computer codes used to obtai...

A coupled lattice BGK model for the Boussinesq equationsAbstract In this paper, a thermal lattice BGK model is developed for the Boussinesq incompressible fluids. The basic idea is to solve the velocity field and the temperature field using two independent lattice BGK equations, respectively, and then combine them into one coupled model for the whole system. The porous plate problem and the two‐dimensional natural convec... ... hiện toàn bộ

Finite volume multigrid prediction of laminar natural convection: Bench‐mark solutionsAbstract A finite volume multigrid procedure for the prediction of laminar natural convection flows is presented, enabling efficient and accurate calculations on very fine grids. The method is fully conservative and uses second‐order central differencing for convection and diffusion fluxes. The calculations start on a coarse (typically 10 × 10 control volumes) grid ... ... hiện toàn bộ

A test problem for outflow boundary conditions—flow over a backward‐facing stepAbstract A numerical solution for steady incompressible flow over a two‐dimensional backward‐facing step is developed using a Galerkin‐based finite element method. The Reynolds number for the simulations is 800. Computations are performed on an extended channel length to minimize the effect of the outflow boundary on the upstream recirculation zones. A thorough mesh... ... hiện toàn bộ

A general algorithm for compressible and incompressible flow—Part I. the split, characteristic‐based schemeAbstract The paper outlines the formulation of a novel algorithm which can be used for the solution of both compressible and incompressible Navier‐Stokes or Euler equations. Full incompressibility can be dealt with if the algorithm is used in its semi‐explicit form and its structure permits arbitrary interpolation functions to be used avoiding the Babuška‐Brezzi res... ... hiện toàn bộ
