The aim of the subject is developing skills for the simulation and analyses of multiphase flows in complex geometries of components in energy plants.

Students are trained to develop mathematical models of multidimensional multiphase flows, to solve these models with computational multi-fluid dynamic methods and to conduct simulation and analyses with the aim of designing and analyzing the operation of equipment of complex geometry in energy plants.

Balance equations for multiphase flow. Closure laws for interfacial transport phenomena. Control volume based numerical methods. SIMPLE type solving algorithms. Interface tracking techniques.

Computer simulations of boiling two-phase flows in steam generators and heat exchangers.

Attended courses in Fluid Mechanics, Thermodynamics and Numerical methods within maser or doctoral studies.

Course handouts. Computer equipment. Software for numerical solving of systems of differential equations of various types. Software for simulation and analyses of pressure transients in pipeline networks and pressurized vessels. Software for simulation and analyses of multidimensional two-phase flows.
