Title: SURFACE CONSTANT-TEMPERATURE ANEMOMETER SENSORS USED TO ANALYZE PARTICLE IMAGE VELOCIMETRY DATA.
Authors: Vishnyakov, O. I.1 (AUTHOR), Polivanov, P. A.1 (AUTHOR), Bountin, D. A.1 (AUTHOR) bountin@itam.nsc.ru
Source: Journal of Applied Mechanics & Technical Physics. Apr2024, Vol. 65 Issue 2, p274-278. 5p.
Subjects: Mach number, Transonic flow, Boundary layer (Aerodynamics), Shock waves, Unsteady flow, Particle image velocimetry
Abstract: This paper describes a new method for performing the time-frequency analysis of particle image velocimetry data with account for surface constant-temperature anemometer sensor readings. This method is based on calculating correlation coefficients between particle image velocimetry data and constant-temperature anemometer data, previously filtered in a given frequency range. This approach makes it possible to obtain data on the unsteady characteristics of flows throughout the entire measurement range in a frequency range whose boundaries extend beyond the boundaries of the particle image velocimetry frequency range. The proposed method is applied to study nonstationary processes in a region where a shock wave interacts with a boundary layer at a Mach number M = 1.43. [ABSTRACT FROM AUTHOR]
