Viktor Schauberger's vortex engine
According to some reports a flying saucer-like experimental vortex engine designed by Viktor Schauberger had a very impressive test flight during last days of WWII. Is this true? We do not know and do not have means verify whether this is true or not. But what can be done by engineers is determining whether this potentially could be true (i.e. if such engine can work or not). The objective of this topic is to analyse the performance of the engine from the first principles of thermodynamic and fluid mechanics and making small simple models dealing with "vortex propulsion".
Various aspects of turbulent combustion modelling
Investigation involving most recent and promising models designed to deal with turbulent combustion.
Various applications and techniques can be involved.
Underground coal gasification
Investigation into promising new technology that would enable economically efficient and ecologically clean mining of coal. The topics in this area involve search for information, some elements of design and, at the highest level, some simple modelling.

Viktor Schauberger's vortex engine
According to some reports a flying saucer-like experimental vortex engine designed by Viktor Schauberger had a very impressive test flight during last days of WWII. Is this true? We do not know and do not have means verify whether this is true or not. But what can be done by engineers is determining whether this potentially could be true (i.e. if such engine can work or not). The objective of this topic is to analyse the performance of the engine from the first principles of thermodynamic and fluid mechanics and making small simple models dealing with "vortex propulsion".
Various aspects of turbulent combustion modelling
Investigation involving most recent and promising models designed to deal with turbulent combustion.
Various applications and techniques can be involved.
Underground coal gasification
Investigation into promising new technology that would enable economically efficient and ecologically clean mining of coal. The topics in this area involve search for information, some elements of design and, at the highest level, some simple modelling.
Tornadoes and cyclones in atmosphere
Investigation in Fluid Mechanics aspects of atmospheric vortices involving collecting and analyzing the data and, in future, may be some simple simulations.
Ranque-Hilsch Vortex Tube
This is a device that does not have any moving parts and does not need electricity. Air is supplied into the tube at the room temperature and is ejected in two streams - one hot one cold. Do not make mistakes - the device does not contradict the laws of thermodynamics and, in fact, we have one in our lab. Different explanations how it works have been suggested but you will search for the only one which is correct.
