چکیده
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.

15 صفحه اولInfluence of Torque on the Lift and Drag of a Particle in an Oscillatory Flow
In [1] and [2] we computed the lift and drag forces on a sphere, subjected to a wall-bounded oscillatory flow. The forces were found as a function of the Reynolds number, the forcing frequency, and the gap between the particle and the ideally smooth rigid bounding wall. Here we investigate how the forces change as a function of the above parameters and its moment of inertia if the particle is a...
متن کاملInfluence of Wall Proximity on the Lift and Drag of a Particle in an Oscillatory Flow
We report on the lift and drag forces on a stationary sphere subjected to a wall-bounded oscillatory flow. We show how these forces depend on two parameters, namely, the distance between the particle and the bounding wall, and on the frequency of the oscillatory flow. The forces were obtained from numerical solutions of the unsteady incompressible Navier-Stokes equations. For the range of param...
