Abstract: In the present contribution the effect of the particle shape on various jump characteristics is quantified by analyzing data of Direct Numerical Simulations of a large number of mobile mono-disperse particles of realistic properties with only the particle shape being changed between the simulations. Two geometrical shapes were used, sphere, and an ellipsoidal shape representing an average over a typical sediment sample. The analysis provides a quantification of the different behavior of the particles under the present conditions. For example, it is observed that ellipsoidal particles travel further in a jump, while spherical particles take small jumps but more often. The devised setups allow to investigate fundamental issues of the behavior which may provide hints on what can be expected in a realistic sediment with a distribution of size and shape.
