A PDF description of turbulent plane couette flow

Zuu‐Chang Hong, Ching Lin, Ming‐Hua Chen

A transport equation for the one‐point velocity probability densityfunction (pdf) of turbulence is derived, modelled and solved. The new pdfequation is obtained by two modeling…

Thermal and fluid‐dynamic behaviour of double‐pipe condensers and evaporators—a numerical study

F. Escanes, C. D. Pérez‐Segarra, A. Oliva

This paper deals with a numerical simulation of the thermal andfluid‐dynamic behaviour of double‐pipe condensers and evaporators. Thegoverning equations of the fluid flow…

Transport of a condensable species in nonisothermal tube flow

Young Kag Kim, Sang Soo Kim

We present the equations for condensation in cooled upward laminar flowin tubes and consider their solution for low vapour concentrations andvariable vapour‐gas thermodynamic…

Fast fourier transform of spectral boundary elements for transient heat conduction

L.R. Hill, T.N. Farris

The spectral boundary element method for solving two‐dimensionaltransient heat conduction problems is developed. This method is combined withthe fast Fourier transform (FFT) to…

Convective heat transfer in axisymmetric porous bodies

Rajesh Rajamani, C. Srinivas, P. Nithiarasu, K.N. Seetharamu

A finite element method employing Galerkin’s approach is developed toanalyze free convection heat transfer in axisymmetric fluid saturated porousbodies. The method is used to…

Combined forced and free laminar convective heat transfer from a vertical plate with coupling of discontinuous surface heating

Koki Kishinami, Hakaru Saito, Jun Suzuki

Combined free and forced laminar air convective heat transfer from avertical composite plate with isolated discontinuous surface heating elementshas been studied numerically and…
