Aleksieienko S. Numerical modelling of hydroaerodynamic and heat mass transfer processes in areas with free boundaries

The object is subsonic and transonic flows of a viscous stream with free boundaries. The dissertation purpose is development of mathematical models, techniques, algorithms and the programs describing of hydroaerodynamics and heat mass transfer processes in the presence of free boundaries. The method is a numerical simulation on the base of Navier-Stokes equations. Scientific novelty is the developed methods and methodically-programmed complex, which can be used at the decision of a wide range of problems in the presence of free boundaries and phase transitions in quasistationary and non-stationary statements: crystal growing, defrosting of porous medium, profiles icing. Are reproduced the typical forms of ice overgrowths on a surface of the cylinder and a wing profile. Practical value of work: the developed methodically-programmed complex were used on "MOTOR SICH" company for the analysis of perspective anti-icing systems, an assessment of influence of heating of a streamline surface on processes of an icing, definition of zones of the heating providing effective work of anti-icing systems. Scope - the learning process, the development of numerical methods, design and construction work.
