Analytic computations of nonideal corrections to blast wave overpressure predictions at high altitudes

摘要

In this paper, the effects of temperature, pressure, winds, moisture, and molecular content on the propagation of blast waves at high altitudes are investigated. These cause refractions and attenuations which modify the recorded ground overpressures from the ideal predictions. By coupling these effects together, the nonideal corrections to the overpressures are estimated by applying approximations which are dependent on the angle of propagation of the blast wave. Key Points Computes analytically the non-ideal corrections to over pressure predictions Considers atmospheric attenuation and refraction Develops on work done by Reed et al. which has been published in this journal
