The unsteady wake of a wall-mounted rectangular prism at large incident (yaw) angles is investigated numerically at Reynolds number of 250. The incident angles considered here ranged between $0^{\circ }$ and ${45}^{\circ }$, which altered the wake dynamics substantially. A symmetric steady wake at small angles transforms into an asymmetric unsteady wake with complex structures at large angles. Approaching ${40}^{\circ }$, the wake appears weakly unsteady with small amplitude fluctuations in velocity and forces. At ${45}^{\circ }$, however, the wake is dominated by unsteady formation of helical structures with a dominant Strouhal number of ${\mathrm{St}}_v=0.14$ that are formed by the interaction of tip vortices on the front and windward edges of the prism. There also exists an embedded low-frequency mechanism that corresponds to the formation and suppression of unsteady helical structures in the wake. This mechanism creates a low-frequency signature in the wake at ${\mathrm{St}}_l=0.011$. A skeleton model is developed and proposed for the wake that characterizes coherent structures at large incident angles. Furthermore, a more representative length scale is proposed based on the projected width of the prism. The range of Reynolds number based on this new scale varies between 208 and 885 with increasing incident angle.

Particle-laden jet flows can be observed in many industrial applications. In this investigation, the horizontal motion of particle laden jets is simulated using the Eulerian–Lagrangian framework. The two-way coupling is applied to the model to simulate the interaction between discrete and continuum phase. In order to track the continuum phase, a passive scalar equation is added to the solver. Eddy Life Time (ELT) is employed as a dispersion model. The influences of different non-dimensional parameters, such as Stokes number, Jet Reynolds number and mass loading ratio on the flow characteristics, are studied. The results of the simulations are verified with the available experimental data. It is revealed that more gravitational force is exerted on the jet as a result of the increase in mass loading, which deflects it more. Moreover, with an increase in the Reynolds number, the speed of the jet rises, and consequently, the gravitational force becomes less capable of deviating the jet. In addition, it is observed that by increasing the Stokes number, the particles leave the jet at higher speed, which causes a lower deviation of the jet.
