“…For a given probe, the flow coefficient varies with the operating conditions including fluid velocity, density and viscosity [82] and is usually given empirically by the manufacture. Apart from these external factors, the cross-sectional shape and relative positions of the openings can also dramatically change the characteristics of the Pitot tube, which has been extensively studied in [83][84][85][86][87].…”

“…The observed characteristics are consistent over a large range of flow under all cases, making it possible to use a constant flow coefficient value in practice. [87] conducted numerical studies to investigate the effect of APT probe shape on the permanent pressure loss. 4 types of APT were tested to find the optimum shape that maximizes the differential pressure while minimizing the permanent pressure loss.…”

To meet the demand for the accurate measurements of the dynamic pressure of a shock wave, a composite dynamic pressure sensor design method is proposed based on the formation mechanism, propagation characteristics, special testing environment of the dynamic pressure, and Pitot tube structure. The dynamic pressure of the shock wave is evaluated by the total pressure and static pressure units installed in the composite sensor. FLUENT simulation software was used to analyze the aerodynamic characteristics of the dynamic pressure sensor, and parameters such as the structural size and inlet position of the sensor were determined. In response to the special experimental environment of the shock wave, the requirements for the dynamic pressure measurements under damage conditions were analyzed, and a dynamic pressure testing system was established. Dynamic pressure tests with four 2,4,6-trinitrotoluene [C7H5(NO2)3] equivalents of 1, 2, 15, and 20 kg were carried out. The experimental results show that the proposed sensor design method can accurately and effectively measure the dynamic pressure signal, and the dynamic pressure gain multiple decreases with an increase in the proportional distance. This provides an effective testing method for evaluating the dynamic pressure damage effect of ammunition systems.
