Аннотация

In order to study the interaction between finite size particles and wall turbulence, the influence of the walls on the flow around 2D and 3D obstacles is analysed. The flow is simulated by an efficient Fourier Chebyshev method. The obstacle is accounted for by an implicit penalty method. The case of a cylinder at different distances to the wall and the case of a sphere in the middle of the channel are computed. For both test cases, the results of the simulations are in good agreement with other studies.
