Effect of rough wall on drag, lift, and torque on an ellipsoidal particle in a linear shear flow

The present study provides a detailed description of the forces on an ellipsoidal particle in vicinity rough wall. Three-dimensional numerical simulations are performed using body-fitted mesh to estimate drag, lift, and torque coefficients. A large number conducted over range parameters, such as shear Reynolds ([Formula: see text]), orientation angle wall-particle separation distance get comprehensive variation above Using simulation results, we develop correlations for drag lift coefficients describe effect wall, inclination angles, numbers hydrodynamic proposed can be used two-phase flow Eulerian–Lagrangian framework.
