| Popis: | The interaction of a shock wave with a laminar boundary layer was studied at the low supersonic Mach number M = 1.43. The measurements were carried out by particle image velocimetry and hot-wire anemometry. The wide range of Mach numbers in the shear layer occurring in the interaction zone made the analysis of hot-wire anemometer data much more difficult. The paper proposes the method of processing of the hot-wire anemometer data involving the simplified sensor calibration and the data obtained by the particle image velocimetry measurements. Good agreement of the results obtained by two experimental techniques is demonstrated. The data gathered in this work permit simplifying essentially the usage of the hot-wire anemometer technique applied for the study of transonic shear flows. |
