Formulation of boundary element method for calculation of heat accumulated in homogenous body / B. Obsieger

Public ISBD Accompagne Advanced concepts and techniques in thermal modelling / J. Henriette Titre : Formulation of boundary element method for calculation of heat accumulated in homogenous body Type de document : texte imprimé Auteurs : B. Obsieger, Auteur Année de publication : 1998 Importance : p 207-214 Langues : Anglais (eng) Catégories : MATHEMATIQUE-PHYSIQUE-CHIMIE Mots-clés : TRANSFERT DE CHALEUR  BOUNDARY ELEMENT METHOD (BEM)  CONDUCTION DE CHALEUR  EQUATION DIFFERENTIELLE Résumé : The evaluated method allows calculation of accumulated heat in homogenous isotropic body without calculation of temperature field in the body, by simple integration of boundary conditions. Unknown boundary conditions are related to predetermined boundary conditions by integral equation of equilibrium, which can be reduced to the ordinary system of linear equations by dividing boundary into boundary elements. A few additional expressions for calculation of temperature field are also presented.

Numerical simulation of time-periodic convective flows in an infinite horizontal porous layer / F. Dufour

Public ISBD Accompagne Advanced concepts and techniques in thermal modelling / J.

They are travelling waves and front-like modulated rolls, with wavelengths in an interval. A numerical study which is the topic of this paper allows to describe the corresponding flows above the convective threshold.

Instantaneous and time averaged 3D flow and temperature structure in 2D ribbed channels / U. Muller

Reynolds number, the lateral boundary conditions and the width of the channel have been varied. Results indicate that both instantaneous and time averaged three dimensional structures appear irrespective of the lateral boundary conditions (symmetry or periodicity).

The radiation model is based on the discrete ordinate method for gray media. The momentum, energy and discrete ordinate equations are solved with the finite element method. The need for an upwind scheme in complex geometries and the implementation of specular and diffuse reflecting walls in the radiation model are discussed. The model is applied to the combined heat transfer problem in a lighting armature.
