NATURAL CONVECTION HEAT TRANSFER IN INCLINED TALL CAVITIES BOUNDED BY POROUS LAYERS

M. HASNAOUI, P. VASSEUR, E. BILGEN

Thermally driven flow in a tall inclined cavity bounded by porous layers is studied analytically and numerically. A constant heat flux is applied for heating and cooling of two…

TRANSIENT THERMOELASTICITY BY MULTIPLE RECIPROCITY METHOD

A.C. NEVES, L.C. WROBEL, A.J. NOWAK

This paper presents a boundary element formulation for transient uncoupled thermoelasticity employing a multiple reciprocity method (MRM) approximation for calculating the thermal…

FINITE ELEMENT MODELLING OF THE ‘NEAR WALL ZONE’ OF CONFINED TURBULENT FLOWS: PART II

C. TAYLOR, J.Y. XIA

Finite element based solution techniques have been developed to replace the conventional ‘wall functions’ in the ‘near wall zone’ of general confined turbulent flows. The…

NATURAL CONVECTION IN PARTITIONED ENCLOSURES WITH LOCALIZED HEATING

E. NTIBARUFATA, M. HASNAOUI, E. BILGEN, P. VASSEUR

The aim of the present investigation was to study numerically the natural convection in partitioned enclosures with localized heating from below. Two‐dimensional equations of…

DUAL RECIPROCITY BOUNDARY ELEMENT METHOD FOR THE TIME‐DEPENDENT STOKES FLOWS

HENRY POWER, PAUL W. PARTRIDGE

This paper presents a boundary element formulation for the transient Stokes equations in which the well known closed form fundamental solution to the steady Stokes equations is…

APPLICATION OF THE HOMOGRAPHIC APPROXIMATION IN THE ENTHALPY METHOD FOR PHASE CHANGE PROBLEMS

MINWU YAO, ARNON CHAIT

The homographic approximation, in which the Heaviside step function is replaced by a continuous smooth curve, is applied to the enthalpy method for heat transfer problems with…

TRANSIENT TEMPERATURE DISTRIBUTION IN ROTARY REGENERATOR HEAT EXCHANGER

ITSURO SAKAI, YOSHIHIRO KAWAGUCHI

The purpose of this study is to analyse dynamic response of rotary regenerator for dynamic simulation of automotive gas turbine using a simplified method. Exit temperatures of…
