December 2018: Pedram's latest research work, supported by NASA, was accepted for publication in International Journal of Multiphase Flow! Congratulations Pedram! In this work, we evaluate a regime of dispersed particle-laden flow modelling on the Elghobashi map (figure of Stokes number versus volume loading identifying different inter-phase couplings) for which the fluid volume/mass displaced by subgrid point particles is important. For particle volume loading of more than 5%, it was found that the fluid phase incompressible Navier Stokes equations typically employed for the point-particle modeling, should be modified to account for the spatio-temporal variations in local volume fractions. Observations are obtained for a test case of densely loaded particle-laden jet which has direct implications for applications involving liquid sprays and secondary atomization. The paper maybe found here here.

With confinement, long time fluid particle trajectories are restricted to certain paths that depend on the topology! Congratulations Bryan! The paper may be found here.
