1. Bearing and hydrodynamic gap with elastic lining

   Aim of the PhD study is design of journal bearing and hydrodynamic sealing gap with elastic lining. It is a coupled hydroelasticity problem. Tensors of the added actions (mass, damping, stiffness) will be the solution results. Interaction between the elastic lining and rheological fluid is assumed. The thesis will be supported by a grant project of the Ministery of Trade and Industry.

2. Cavitating vortical structures

   Vortical structures arising in hydraulic machines are locations of very low pressure where, eventually, water undergoes a phase change into saturated vapor - cavitation occurs. Aim of the PhD thesis is experimental research and computational modeling of such structures and investigation of conditions, which influence their origin.

3. Development of a New Submersible Aerator with Double Inflow Runner.

   The goal of this work is development of new submersible aerator with double inflow runner. This equipment could be used in waste water treatments plants, water treatment plants, fish farming and anywhere where increasing of oxygen rate in fluid is necessary. Runner is designed as double inflow runner. One side of runner is used for water and other side is used for air. The problem of two-phases flow have to be solved in this work.

4. Exploiting cavitation for electric energy production

   Electromagnetic voltage is a result of conductor motion in magnetic field. Flowing fluid is also a conductor in case that the fluid elements are charged. Subject of the PhD study is investigation of the fluid velocity influence on magnitude of magnetic induction under conditions of cavitating bubble collapse. As the frequency of the cavitation bubble collpase are around 24kHz, we may assume significant changes in electromagnetic induction and also electromagnetic voltage. Magnetic field will be formed from permanent magnets, which will be in the vicinity of the tube outer surface.

5. New princiles of journal bearings

   It is an interdisciplinary topic. Study of electric and magnetic fields in interaction with liquid will be the main focus. Various vortical structures occuring in journal bearings will be studied in the first stage. Second stage will be directed toward influencing these structures by magnetic field. Added effects of the previously mentioned physical fields on the rotor will be the research results.

6. Spiral case of impeller pump optimalization.

   Spiral case of an impeller pump is a part of the pump which participate on overall characteristic of the pump. There is an origin of hydraulic losses, radilal force and phenomenons connected with flow in the inner part of the pump. The aim of this theme is minimalization of hydrulic losses and radial force by alternative methods than since used.

7. The bearing on principle of a golf ball and Taylor vortices.

   The aim of doctoral study is a design of new principle of slide bearing based on Taylor vortices study. These vortices are caused by the shape of the rotor (similar as a golf ball). The principle is based on micro-vortices, which rise in consequence of centrifugal force acting on the liquid. Conditions of stability of stationary flow will be studied too. The function of slide bearing is possible after overrunning the stability and creation of Taylor vortices as well. The study will be based on modeling of unsteady turbulent flow and experiment verification. It will be supported by MPO project.

8. The design of a jet on principle of ejector for cooling

   The aim doctoral study is a design of special jet with possibility of air leech onto. The solution will be based on computational modelling two-phase flow in the jet. The jet will be designed with respect to using the cooling (cylinders in rolling of sheet metal, instruments). This study will be supported by MPO project.

9. The design of counter-rotating runners of swirl turbine.

   The swirl turbine is a new type of the turbine for small heads and large discharges and high rotation speed. If head up 3 meters occurs, there is a cavitation danger and the hydraulic energy is necessary to obtain from more number of runners. The design of counter - rotating runners would give the resolution for design of swirl turbine for large head and large discharges and high rotation speed.

10. Valve exploiting principle of the side-channel turbine

    All current valves are source of hydraulic loss. Aim of the PhD study is design of a new hydraulic valve, which will be based on low specific speed turbine. Design of the turbine will reflect the loss characteristic curve of the valve. This will ensure 50% recuperation of the supplied energy. Solution will be based on computational modeling of the turbulent flow and experimental research. PhD study will be financially supported from the frontier region grant project.

11. Verifying of Boundary Vorticity Elements Method with Continuous Distribution of Vorticity on Solution of 2D Fluid Flow Round Single Hydrofoil.

    The Boundary Vorticity Elements Method with Continuous Distribution Vorticity has a promising future in area of vortex fluid flow modeling. This method brings a new aspects and possibilities in this area. Basic theoretical principles of this method have been developed. It is important to verify and the possibilities of this method on the practical examples. It is important to choose proper boundary conditions for vorticity distribution or choose proper method to fulfilling the Kuta-Zukovskij condition of smooth profile outflow.
