The range of v_b expressed in a dimensionless way, υ^*_b = υ_b / √gd_p (where √gd_p is the velocity that a particle reaches when falls a distance equal to its own radius by action of gravity) covers between 0.005 and 0.8. [Google Scholar]

It is possible to build a dimensionless variable b^* = b * √gd_p The result would be b^* = 0.25, a value which is lesser than the one obtained for a. [Google Scholar]

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
