A Generalized Protocol for Computational Simulation of Spray Flows Including Primary Atomization

Popis výsledku v původním jazyce

Using the theoretical result for primary atomization, we have developed a computational protocol for compact and efficient simulations of spray flows. Volume-of-fluid (VOF) is used to map out the pre-atomization liquid flow field. The velocity and liquid contour from VOF is input in the “quadratic formula” to determine the initial drop size, to furnish the initial conditions for the post-atomization discrete-particle simulations (DPS). This approach has worked quite well in pressure-atomized sprays with and without swirl, and in liquid jets in cross flows, as presented in previous ILASS papers and journals. It constitutes a general simulation framework, based on fundamental and validated fluid physics of spray atomization, and leads to a very efficient and compact computational scheme to simulate spray flows in complex geometries. In this paper, we will present application examples in various other spray geometries and discuss potential uses in practical devices and systems, so that the generalizabili
