Abstract 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 error not exceeding 0.5%. The measurement area was 0.1x0.1x0.5mm. The positioning device moved the measuring unit in the area of 250 x 250 x 250 mm with an accuracy of 0.1 mm. This method also provides the ability to measure local flow rate fluctuations.

James Hunter Whitelaw, after an education in Scotland and postdoctoral research in the USA, spent his subsequent career at Imperial College, London, where, over the ensuing 36 years, he led the development of laser–Doppler anemometry and subsequent laser–based instrumentation for flow characterization. These he used to gain insights into the measured behaviour of a multitude of complex turbulent flows encountered in engineering, particularly flows undergoing combustion.
