Statistical properties of spherical shock waves propagating through grid turbulence, turbulent cylinder wake, and laminar flow

Abstract: Wind tunnel experiments are reported for a spherical shock wave propagating through turbulent wakes of a single cylinder, double cylinders, grid-turbulence, and a laminar flow, whose influences on the shock wave are compared. Overpressure behind the shock wave is measured on a plate while streamwise velocity is measured at the flow point between the measurement plate and the location of the shock wave ejection. Average of peak-overpressure observed upon arrival of the shock wave is decreased by the mean veloci… Show more

“…Wind tunnels have been used extensively in many studies [1]- [3] commonly including experimental measurements [4]- [13], numerical simulations [14]- [17], and in various flow situations e.g. subsonic, hypersonic [18], [19], transonic [20], [21], laminar, turbulent [22]- [24], etc. In engineering, wind tunnels are used to test the flow around aircrafts, the performance of rotors and turbines [25]- [27], and even studies on the flight of birds [28] and the effects of wind on the shape and growth of plants [29].…”
