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.
