Analysis and Modeling of Non-Spherical Particle Motion in a Gas Flow

This paper describes the reviews of recent works in analysis, modeling, and simulation motion a non-spherical particle. The particles was analyzed detail by means fully resolved direct numerical (DNS). From DNS data, PDF-based drag coefficient model proposed applied to particle dispersion an isotropic turbulent flow assess effect shape comparing it with spherical Moreover, large-eddy (LES) axial jet validated experimental data. Results showed that clearly observed characteristics evaluating deviation from Poisson distribution (D number) radial function (RDF). It found particle’s representative Stokes number becomes larger as sphericity increases. Furthermore, also revealed effects size experiment precisely captured LES coincided trend flow.
