Summary: Graphic visualisation of 2D and 3D stream flow round propellers by computer aid.Software generation in order to solve problems of designing and analysis of propeler work. Further development of propeller methods and their application on the design of free screw-propellers and screw-propellers with tip plates, nevertheless of other special propellers. Fundamental investigation of the influence of screw-propeller geometry on cavitation development. Study of wake field character influence on propulsion efficiency. Principles of cavitation noise modelling. Development of Boolean equations. Mathematical model of oscillatory ship motion on harmonic wave.

Keywords: Ship screw propeller, screw in nozzle, screw with tip plates, tip vortex, wake field, cavitation, scaling rules, efficiency, noise, visualization, Boolean matrices, sparse matrices, theory of ship motions on wave, Frank close-fit method.

Research goals: Program development to make possible graphic view of fluid stream round propellers, by numerical methods of definition in hydrodynamics. Development of numeric methods in hydrodynamics for application on special types of propellers. Software development in the field of known and new propeller designs. Definition of loading possibilities through the screw disc, which in the wake field composed of viscous and potential components, make achievable the best possible total coefficient of efficiency. Testing of cavitation noise modelling lows on a true experimental material. Solving of Boole's equations. Outwork of mathematical model of oscillatory ship motion on harmonic wave. Achievement of doctor and magister degrees of science.
