SMV-2019-26: Thermacut Course
Mrňa, Libor
Schlieren visualization of flow through laser cutting nozzles with cross section similar to Laval nozzle. Training for Termacut k.s workers on principles of laser cutting.
SMV-2017-08: Investigation of gas flow through laser cutting nozzles, including nozzle life tests in real operation
Mrňa, Libor
The research deals with the study of gas flow through laser nozzles, depending on production tolerances and defects. Flow method will be used to visualize the flow. Nozzles with deliberately introduced manufacturing defects are supplied by the customer. In addition, research into the flow of cutting gas from different types of nozzles through a cutting slot in a glass block (simulating a split metal material) will be carried out. Finally, the life of nozzles made from different types of material will be investigated.
