The volume of fluid method in spherical coordinates

A.M.C. Janse, P.E. Dijk, J.A.M. Kuipers

The volume of fluid (VOF) method is a numerical technique to track the developing free surfaces of liquids in motion. This method can, for example, be applied to compute the…

Experiences in solutions of non‐linear transport equations with the Green element method

Okey Oseloka Onyejekwe

Two Green element approximation schemes are used for the solution of transient non‐linear evolution problems. While the first scheme adopts linear interpolation polynomial to…

An efficient direct BEM numerical scheme for heat transfer problems using Fourier series

Maria T. Ibáñez, H. Power

The main objective is to develop an efficient BEM scheme for the numerical solution of two‐dimensional heat problems. Our scheme will be of the re‐initialization type, in which…

Influence of buoyancy forces on Marangoni flow instabilities in liquid bridges

M. Lappa, R. Savino, R. Monti

The influence of buoyancy forces on oscillatory Marangoni flow in liquid bridges of different aspect ratio is investigated by three‐dimensional, time‐dependent numerical solutions…

Heat transfer study of high speed flow over a spiked blunt body

R.C. Mehta

Unsteady compressible, axisymmetric Navier‐Stokes equations are solved for a flow over a forward facing spike attached to a heat shield for a freestream Mach number range of…

Entropy generation due to laminar forced convection flow past a parabolic cylinder

O.M. Haddad, M. Abu‐Qudais, B.A/K Abu‐Hijleh, A.M. Maqableh

This study is focused on the local entropy generation of steady two‐dimensional symmetric flow past a parabolic cylinder in a uniform stream parallel to its axis. The effect of…
