The seminar will present the recent results of our work on physical and mathematical modelling of pipe flows of settling slurries (slurries with Newtonian carrier) and of complex slurries (slurries with non-Newtonian carrier) in a broad range of flow conditions. Different flow types, patterns and behaviours will be described and demonstrated on experimental observations of flowing slurries of different solids fractions (fine, medium, coarse, very coarse) and pipe geometries (horizontal, inclined, vertical) from test loops in two laboratories in Prague. Special attention will be paid to an internal structure of slurry flow (some flows tend to stratify) and flow conditions at flow boundaries and interfaces.
Appropriate modelling approaches will be discussed for a successful prediction of the frictional pressure drop in flows of particular slurries at particular flow conditions in pressurized pipes.
