Developing turbulent duct flow: hybrid solution via integral transforms and algebraic model

R.M. Cotta, L.C.G. Pimentel

The integral transform method is employed for the hybrid numerical‐analytical solution of the boundary layer formulation in developing turbulent flow inside channels. An algebraic…

Integral transforms in the two‐dimensional non‐linear formulation of longitudinal fins with variable profile

R.M. Cotta, R. Ramos

The integral transform method is employed for the hybrid numerical‐analytical solution of two‐dimensional, steady‐state heat conduction within extended surfaces of variable…

Free convection along a vertical heated plate in a porous medium with anisotropic permeability

P. Vasseur, G. Degan

Natural convection from a semi‐infinite vertical plate embedded in a fluid saturated porous medium is studied both analytically and numerically. The plate is assumed to be heated…

Steady and unsteady computation of a two‐dimensional upwash jet

Seong Ho Cho, Seung O. Park

Computational procedures and results of an upwash jet arising from two opposing plane wall jets based on the Reynolds averaged Navier‐Stokes equations are discussed. For the…

A mixed approach to finite element analysis of hyperbolic heat conduction problems

Mehrdad T. Manzari, Majid T. Manzari

Using a non‐Fourier heat conduction (NFHC) hypothesis, the governing equations of thermal wave propagation are established. The resulting differential equations are transformed to…

Natural convection in an inclined porous cavity with variable porosity and thermal dispersion effects

Shih‐Wen Hsiao

The variable porosity and thermal dispersion effects on natural convection in an inclined porous cavity are investigated numerically. The wall effect on porosity is approximated…

3D numerical investigation of turbulent forced convection in wavy ducts with trapezoidal cross‐section

Masoud Rokni, Bengt Sundén

The present investigation is an extension of the authors’ previous work on ducts with different cross sections. It concerns application of turbulence models for forced convective…
