Numerical simulation of compressible flow induced by a heat and mass source in a partially—open cavity

L. Allançon, B. Porterie, R. Saurel, J.C. Loraud

A numerical analysis is given for the prediction of unsteady,two‐dimensional fluid flow induced by a heat and mass source in aninitially closed cavity which is vented when the…

A bem analysis for transient conduction—convection problems

J. Lim, C.L. Chan, A. Chandra

A boundary element method (BEM) formulation for the solutionof transient conduction‐convection problems is developed in thispaper. A time‐dependent fundamental solution for moving…

An asymptotic solution for the singularity at the angular point of the lid driven cavity

T. Störtkuhl, C. Zenger, S. Zimmer

In this paper, we analyse the behaviour of the solution of theNavier—Stokes equations near the corner of the driven cavity where themoving band touches the wall. At this point…

Finite element simulation of laser surface treatments including convection in the melt pool

M. Picasso, A.F.A. Hoadley

A two‐dimensional, macroscopic, stationary, finite element modelis presented for both laser remelting and laser cladding of materialsurfaces. It considers, in addition to the heat…

Enthalpy gradient methods for capturing latent heat in phase change simulations using biquadratic isoparametric finite elements

J.F.T. Pittman, G.P. Whitham

Methods that use spatial gradients of enthalpy to evaluate effectivespecific heats and capture latent heat effects in phase change problems havebeen used successfully in finite…
