NUMERICAL ANALYSIS OF CONVECTION‐DIFFUSION PROBLEMS USING THE BOUNDARY ELEMENT METHOD

L.C. WROBEL, D.B. DE FIGUEIREDO

This paper presents a boundary element formulation for transient convection‐diffusion problems employing the fundamental solution of the corresponding steady‐state equation with…

GAS FLOWS WITHIN TURNING SECTIONS

R. PLATFOOT, C.A.J. FLETCHER

An alternative algorithm has been developed for computing the behaviour of flows within arbitrary ducts and channels. This technique requires a small number of downstream marches…

MIXED LAMINAR HEAT AND FLUID FLOW IN FLOW‐THROUGH OPENED TRAPEZOIDAL COOLING CHAMBERS OF LOW ASPECT RATIOS

T.S. LEE

Heat and fluid flow through a trapezoidal cooling chamber were studied numerically. Hot fluid is assumed inflow at some depth below the surface into one end of the chamber and…

MULTIGRID SOLUTION OF STEADY EULER EQUATIONS BASED ON POLYNOMIAL FLUX‐DIFFERENCE SPLITTING

ERIK DICK

A flux‐difference splitting based on the polynomial character of the flux vectors is applied to steady Euler equations, discretized with a vertex‐centred finite volume method. In…

HYDRODYNAMIC AND THERMAL ANALYSIS OF RIVULET FLOW DOWN A VERTICAL SOLID SURFACE

KAMEL M. AL‐KHALIL, THEO G. JR. KEITH, KENNETH J. DE WITT

The hydrodynamics and thermal characteristics of a laminar rivulet flow down a vertical surface are investigated. The velocity distribution within a rivulet is determined…

A FRACTIONAL STEP FINITE ELEMENT METHOD FOR CONDUCTIVE‐CONVECTIVE HEAT TRANSFER PROBLEMS

KATSUMORI HATANAKA, MUTSUTO KAWAHARA

A new fractional step method in conjunction with the finite element method is proposed for the analysis of the thermal convection and conduction in a fluid region expressed by the…
