The aim is acquiring knowledge and skills for development and application of analytical and numerical models of thermal-hydraulic processes in energy, thermal and process equipment,as well as application of numerical methods for the simulation and analyses of one-phase and two-phase systems in pipelines and plant equipment, including the methods of Computational Fluid Dynamics - CFD.
The students are trained to perform computer simulation and analyses of heat transfer and fluid flow processes of one-phase and two-phase gas-liquid systems with and without phase transitions in energy, thermal and process equipment.
Modelling of thermal and flow processes with lumped and distributed parameters. Balance equations of mass, momentum and energy and constitutive correlations for interface transfer processes. Explicit and implicit numerical methods for the solving of Cauchy problems with defined initial conditions in cases of the lumped parameter models. The method of characteristics for the solving of hyperbolic system of partial differential equations. The application of the method of control volumes of the SIMPLE type for the solving of elliptic and parabolic multidimensional models with distributed parameters. Numerical grid generation. Graphical presentation of results.
Development of the models with lumped parameters for the pressure dynamics prediction in the pressurized vessels filled with one phase compressible fluid or two-phase mixture of liquid and condensing vapour. Numerical simulation of pressure transients in the pressurizer, in the feedwater tank and the drum of a steam boiler. Development of models with distributed parameters for one-phase and two-phase flows with or without phase transitions. Numerical simulations of pressure and temperature waves propagation in pipeline networks. Computer simulations and analyses of multidimensional two-phase flows in steam generators, evaporators, condensers, heat exchangers, etc.
Attended courses in Fluid Mechanics, Thermodynamics, and Numerical Methods.
