The interaction of small, solid particles with turbulent coherent structures near the walls of a vertical channel is numerically investigated using direct numerical simulation (DNS) together with Lagrangian particle tracking (LPT) and a point-force approximation for the feedback effect of the particles on the fluid. Results from conditional sampling show that the diameter and the streamwise extent...
Results of direct numerical simulations are presented for the strongly transient and turbulent natural convection cooling of an initially isothermal quiescent liquid metal placed in a cylinder under the effect of an external vertical uniform and constant magnetic field. The electrically conductive low Prandtl number fluid is put to motion when the vertical sidewall is suddenly cooled to a uniform...
