Drag coefficient of spherical particles in turbulent channel flow
Result description
The paper presents results of numerical calculations of drag coefficients of large spherical solid particles. Several hydraulic cases were tested. The first one - the spheres were fixed at different heights above a rough bed of an open channel, the second one - the spheres moved along the channel bed and the third one - the sphere impacted and rebounded from a smooth surface. Finite Volume and Lattice Boltzmann methods were used for the simulations. The Particle Image Velocimetry (2D-PIV) was used to determine the velocity field in the open channel.
