Axisymmetric finite element models for rotational molding

Lorraine G. Olson, George Gogos, Venkataramana Pasham

We present a new nonlinear axisymmetric finite element model for heat transfer and powder deposition in rotational molding. Arbitrary Lagrangian Eulerian techniques are employed…

Bifurcation in steady laminar mixed convection flow in uniformly heated inclined tubes

J. Orfi, N. Galanis, C.T. Nguyen

The fully developed laminar mixed convection flow in inclined tubes subject to axially and circumferentially uniform heat flux has been studied numerically for a Boussinesq fluid…

Free convection flow of thermomicropolar fluid along a vertical plate with nonuniform surface temperature and surface heat flux

M. A. Hossain, M.K. Chowdhury, R.S.R. Gorla

We determine the effects of micro‐inertia density and the vortex viscosity on laminar free convection boundary layer flow of a thermomicropolar fluid past a vertical plate with…

Preconditioning by approximations of the discrete Laplacian for 2‐D non‐linear free convection elliptic equations

Gh. Juncu

The paper analyses the preconditioning of non‐linear nonsymmetric equations with approximations of the discrete Laplace operator. The test problems are non‐linear 2‐D elliptic…

Nonsimilar solutions for mixed convection in non‐Newtonian fluids along a wedge with variable surface temperature in a porous medium

Rama Subba Reddy Gorla, Mahesh Kumari

A nonsimilar boundary layer analysis is presented for the problem of mixed convection in power‐law type non‐Newtonian fluids along a vertical wedge with variable wall temperature…

Finite element simulation of transient natural convection of low‐Prandtl‐number fluids in heated cavity

Habib Sammouda, Ali Belghith, Claude Surry

The aim of the present investigation was to study numerically the transient of thermal convection in a square cavity filled with low‐Prandtl‐number fluids. The flow is driven by…
