A Maximum Entropy Moment Closure Approach to Describing Spray Flows

Abstract

This paper describes a method to obtain a complete description of a spray flow by computing the evolution of its probability density function simultaneously with the gas flow in which it is embedded. Transport equations describing the evolution of certain moments of the probability density function are closed using a Maximum Entropy Formalism. Work is currently underway to test whether this method will yield significant advantages over conventional approaches to predicting spray flows.
