Parallelization of the finite volume method for radiation heat transfer

P.J. Coelho, J. Gonçalves

The finite volume method for radiative heat transfer calculations has been parallelized using two strategies, the angular domain decomposition and the spatial domain…

A numerical simulation of measured transient temperatures in the walls, floor and surrounding soil of a buried structure

M.H. Adjali, M. Davies, J. Littler

Presents the results of a numerical simulation of measured heat transfer through a region surrounding a buried structure. The model applied in the study is a widely used whole…

Interaction of surface radiation and variable property natural convection in a differentially heated square cavity – a finite element analysis

S.K. Mahapatra, S. Sen, A. Sarkar

A finite element solution on the interaction of surface radiation and variable property laminar natural convection is presented. Finite element formulation of the governing…

Transient conjugate heat transfer in a porous medium in concentric annuli

M.A.I. El‐Shaarawi, M.A. Al‐Nimr, M.M.K. Al Yah

Transient conjugated forced convection in the thermal entry region of a thick‐walled annulus, filled with a homogeneous and isotropic porous medium, has been numerically…

ADM‐WENO scheme and its application in compressible mixing flows

Haidong Li, Weng Kong Chan

High order schemes, which are widely used in DNS and LES, received increasing attention in recent years with a number of variants being developed. However most of these schemes…

Estimation of numerical accuracy for the flow field in a draft tube

John Bergström, Rikard Gebart

The potential for overall efficiency improvements of modern hydro power turbines is a few percent. A significant part of the losses occurs in the draft tube. To improve the…

Numerical study on oscillatory convection of cold water in a tall vertical enclosure

C.J. Ho, F.J. Tu

The stability of two‐dimensional natural convection of water near its density maximum (cold water) inside a vertical rectangular enclosure with an aspect ratio of eight is…
