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.

Radiative-convective heat transfer in a reacting bow shock layer / R. Vaillon

Total radiative local sources and fluxes functions are accurately determined by using a special frequency integration method associated to an up to date absorption spectrum and the Discrete Ordinates Method on Orthogonal Curvilinear Coordinates (DOM-OCC) accounting for the curvature of the body. As a result for an hydrogen-helium atmosphere, the net relative fluxes profile upon a black surface of a body and the radiative sources field within the layer are worked out.

New algorithm for the discrete ordinates method : application to anisotropic scattering media of irregular geometry / M. Sakami

Public ISBD Accompagne Advanced concepts and techniques in thermal modelling / J. Henriette Titre : New algorithm for the discrete ordinates method : application to anisotropic scattering media of irregular geometry Type de document : texte imprimé Auteurs : M. Sakami, Auteur ; A.

A gray absorbing, emitting and anisotropically scattering medium is enclosed in cavities of regular and complex geometry. The phase function is approximated by a finite series of Legendre polynomials. The key feature of the new technique is the utilization of general characteristic equations which replace the classical spatial differencing schemes and makes possible the use of triangular grids which can be fitted to any geometrical enclosure. An assessment of the method is given by comparing the results with those obtained by other authors . The method proves to be general and accurate.
