About OpenFOAM

OpenFOAM is a free, open source computational fluid dynamics (CFD) software package released by the OpenFOAM Foundation. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.

Acoustic Streaming Application

This repository contains developments for modeling direct-chill (DC) casting by Bruno Lebon at BCAST, Brunel University London using OpenFOAM.

This work includes a solver based on:

F.J. Trujillo, "A strict formulation of a nonlinear Helmholtz equation for the propagation of sound in bubbly liquids. Part I: theory and validation at low acoustic pressure amplitudes", Ultrason. Sonochem. 47 (2018) 75-98.

as well as a tutorial case whose geometry corresponds to the case in:

T. Subroto, G.S.B. Lebon et al., "Numerical modelling and experimental validation of the effect of ultrasonic melt treatment in a direct-chill cast AA6008 alloy billet", Journal of Materials Research and Technology 12 (2021) 1582-1596.
