Influence of particle shapes on their fall velocity
The fall velocity is an important property of a sediment of suspension. The fall velocity must be known before the modern concepts of sediment distribution and sediment transportation in a stream can be evaluated. Based on experiments with disks and spheres in different fluid media, it is known that the forces acting on particles can be quite adequately by three dimensionless parameters, namely: Reynolds Number, Re Drag Coefficient, CD Shape Factor, sf Recent investigations carried out to determine the shape factor of natural sediment particles indicate that the shape is an important factor in ...
