Web15 Jun 2024 · 1. Introduction. Shock waves are produced when a projectile flies supersonically in the air. In wind tunnel experiment, it has been observed that as a steady supersonic flow moves past a conical object, a conical shock is produced around the conical object, attached to the head if such object has a sharp pointed tip, otherwise, the shock … WebThe acoustic energy of a shock wave pulse is given in millijoules (mJ). As a rule, several hundred or thousand shock wave pulses are applied per treatment session. This means that the total amount of energy applied is calculated through multiplication by the number of pulses. 1,8 Energy flux density (ED) Web7 May 2024 · Hypersonic Aerodynamics Index.
