Formation and behavior of aeolian streamers
WebThe mechanism, however, by which ( a) the grains composing this cloud are raised, ( b) the rate of mass movement of the sand depends upon the wind velocity, or ( c) the wind velocity close to the surface is affected by the presence of the sand cloud, does not appear to have been previously investigated experimentally. WebAeolian sand transport near the surface in the field often occurs in the form of sand streamers, which is very important to understand in‐depth the physics of aeolian transport and accurately predict the sand transport rate. In this paper, sand streamers were successfully reproduced by combining the Lagrangian trajectory simulation of particles …
