Modelling of turbulent transport in arc welding pools

Nilanjan Chakraborty, Suman Chakraborty, Pradip Dutta

In this paper, we present a modified k‐ε model capable of addressing turbulent weld‐pool convection in the presence of a continuously evolving phase‐change interface during a gas…

A second order finite volume technique for simulating transport in anisotropic media

Jayantha Pasdunkorale A., Ian W. Turner

An existing two‐dimensional finite volume technique is modified by introducing a correction term to increase the accuracy of the method to second order. It is well known that the…

Modelling natural and mixed convection in obstructed channels

Marcela Cruchaga, Diego Celentano

The modelling of steady‐state natural and mixed convection in obstructed channels is presented. The two‐dimensional numerical analysis is carried out with a finite element…

Mixed convection boundary‐layer flow from a horizontal circular cylinder in micropolar fluids: case of constant wall temperature

Roslinda Nazar, Norsarahaida Amin, Ioan Pop

The laminar mixed convection boundary‐layer flow of a micropolar fluid past a horizontal circular cylinder in a stream flowing vertically upwards has been studied in both cases of…

Numerical simulation of heat transfer of turbulent impinging jets with two‐equation turbulence models

Bart Merci, Jan Vierendeels, Chris De Langhe, Erik Dick

A numerical scheme that has already proved to be efficient and accurate for laminar heat transfer is extended for turbulent, axisymmetric heat transfer calculations. The extended…

A linelet preconditioner for incompressible flow solvers

Orlando Soto, Rainald Löhner, Fernando Camelli

A parallel linelet preconditioner has been implemented to accelerate finite element (FE) solvers for incompressible flows when highly anisotropic meshes are used. The convergence…
