Project Description
In this study, the momentum is mainly transferred from the liquid to the gas. The velocity gradient at the interface creates a thin boundary layer in the gas phase. Resolving this boundary layer is currently out of reach of the usual LES meshes of injectors, and remains a challenge for the actual interface modeling techniques. Resolving accurately such a range of scales for the liquid, and the small turbulent scales for the gas, requires tremendous computing resources.
The objectives of this work are:
– to demonstrate scalability of the OpenFOAM solver for large-scale simulations. – to investigate the fundamental mechanisms driving primary atomization of a viscous low velocity liquid entrained by high-speed air for an injector that cap- tures representative physics for a gasification type injector.
