Research on particle size distribution in rectangular turbulent channel flow
Large eddy simu lations of threedimensional particle-laden turbulent channel flow are performed for Re = 13800. The flow results are validated using the experimental data and good agreements are achieved. TEMOM is employed to deal with PGDE, which describes PSD, involving the effect of shearinduced coagulation, which is greatly affected by the effects of turbulent transport and preferential concentration, represented by radial relative velocity and radial distribution function, respectively. Particles with four different stokes number are considered to study the above effects on the evolution of PSD. In the results,the distributions of particle number concentration, polydispersity, particle diameter are detailed discussed.
