Numerical Simulation of Peak Overpressure and Positive Pressure Time of Explosion Shock Wave in the Air

Abstract:

A new rational peak overpressure formula about scale distance has been summarized by comparing differences of domestic and foreign scholars’ empirical formula. AUTODYN has been used to simulate the shock wave in the air by taking different mesh sizes. Comparing the numerical simulation results and empirical formula results, only when the scale distance is too small, two results about peak overpressure have certain deviation. But both results about positive pressure time are similar.
