Abstract
Results of experimental and simulation investigations of hydrodynamic processes of auxiliary gas flow out of nozzles nd stream of products of erosion from the cut slot using laser cutting are presented. Practicability of mathematical modeling of the processes by solving Navier-Stokes equations using simulation programs 'APTEK' and 'PHOENICS 1.4' is shown. Calculation results were validated on full-scale models in hydrodynamic test loop tunnel. Results of modeling then were used in situ, when compressor valves were manufactured using laser cutting of sheets of stainless steel 30X13. Laser cutting was carried out using laser technological unit created on the basis of pulse solid state laser LIT-100M.
