Development of Blast-Wave Mediated Vaccine Delivery Device

Shockwaves are essentially non-linear waves that propagate at supersonic speeds. Such disturbances occur in steady transonic or supersonic flows, during explosions, earthquakes, hydraulic jumps and lightning. Rapid movement of piston in a tube filled with gas generates a shock wave. Any sudden release of energy (within few μs) will invariably result in the formation of shock waves since they are one of the efficient mechanisms of energy dissipation observed in nature. The dissipation of mechanical, nuclear, chemical, and electrical energy in a limited space will usually result in the formation of a shock wave. Because of the dissipative nature of shock waves they invariably need a medium both for generation as well as for propagation.
