Stochastic analysis of particle-fluid two-phase flows

This paper is devoted to exploring approaches to understanding the stochast ic characteristics of particle-fluid two-phase flow. By quantifying the for ces dominating the particle motion and modelling the less important and/or unclear forces as random forces, a stochastic differential equation is prop osed to describe the complex behavior of a particle motion. An exploratory simulation has shown satisfactory agreement with phase doppler particle ana lyzer (PDPA) measurements, which indicates that stochastic analysis is a po tential approach for revealing the details of particle-fluid flow phenomena .
