Research
- Development of an electromagnetic -thermal method for non-destructive testing that combines electromagnetic excitation of the work-piece, heating of the material by induction and inspection by transient infrared thermography. Numerical investigation of the method by considering various types of coils for the excitation of two- and three-dimensional work-pieces. Experimental investigation of the method by eddy current thermography.
- Induction heating systems. Coil design for magnetic field creation.
- Heat exchangers – Thermodynamic cycles (in collaboration with the “Thermal Engines” Laboratory). Development of the Isochoric, Counter-Current Heat Exchanger, a mechanism capable of implementing the thermodynamic process of regenerative preheating in the Lenoir cycle. The introduction of this mechanism may lead to a modified Lenoir cycle with a real efficiency comparable to that of the combined cycles employed in modern Power Plants.
