Transport behaviour of solids

Concentration distribution of the solids (3)

Subsequently, the transport states in relation to the average flow velocity, shown in the figure, are explained further:

Transport state a), floating motion is characterized by a high solids concentration. In this phase, the mean flow velocity of the mixture flow (vm) is much greater than that of the minimum required flow velocity (vc) for a deposit free condition. Maintaining this transport condition requires high flow rates [SteinR2005] [Führb62].
