What is 2021 The 5th International Conference on Compute and Data Analysis about?

The dynamic flow quality is an important performance parameter of wind tunnels, which is directly related to the ability of wind tunnels to be applied to basic aerodynamic research. The probe calibration wind tunnel (PCWT) is a research wind tunnel equipment used to calibrate various pneumatic probes and hot-wire probes. According to its usage, the dynamic flow quality of the PCWT will directly affect the accuracy of the dynamic calibration results of the high-frequency response probes. In this paper, a dynamic flow quality solution and a hyperbola fitting method is established to comprehensively measure and solve the dynamic flow quality of the PCWT. The velocity fluctuation, density fluctuation and total temperature fluctuation within the range of 0.3 to 0.8 of Mach number are evaluated, and the changing law of dynamic flow quality with Mach number is analyzed in detail. The results of dynamic flow quality values and its changing law with Mach number are reasonable, which verifies the feasibility of applying the method established in this paper to the dynamic flow quality measurement in wind tunnels. ## CCS CONCEPTS • General and reference; • Cross-computing tools and techniques;
