The course aims to provide advanced knowledge of two- and three-phase flows (a combination of phases: liquid – solids (particles) gas) with applications in pressurized pipes and open channels. Fundamental principles are discussed of flow of mixture with particular attention paid to mechanisms governing behaviour of mixture flow (dispersion, sedimentation, boundary friction and inner friction, including effects of Newtonian and non-Newtonian carrier). Theories and on theories based predictive models are introduced and their application demonstrated on practical case studies of e.g. pumping and transport of sludge in technological processes, hydraulic transport of solids in pipelines and launders, or sediment transport in rivers and streams. Also discussed are examples of computation of multiphase flows in commercial software including CFD (Computational Fluid Dynamics) software. In the course, each student submits his/her seminar work on a chosen subject.
