The aim of the work was to develop a laser Doppler anemometry method for high-speed turbulent aerodynamic flow diagnostic. As a result, this allowed us to measure two projections of the velocity vector in the range of 0.1 - 400 m/s with a relative er

Current work is devoted to the development of a device for monitoring the dynamic shape of a power unit. The work is based on the FMCW method. The light source uses a low-coherence semiconductor laser diode. Signal processing is performed on an adapt

The paper deals with aerodynamics of a reacting coal-dust-gas flame in a combustion chamber with a rated output of 50 kW. Spatial distributions of the axial and tangential components of the flame velocity were measured with the help of the laser Dopp

The vortex effect in Ranque-Hilch vortex tube was investigated. Being discovered by G.J. Ranque[1] in l928, the effect still has no adequate generally accepted physical explanation. One of the reasons is connected with the lack of reliable experiment

This paper presents results of a study of vortex wake structures and measurements of instantaneous 3D velocity fields downstream of a triblade turbine model. Two operation modes of flow around the rotor with different tip speed ratios were tested. In
