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