In this paper, the effect of the dust particles on the decay of blast waves is studied in a two-phase, unsteady flow of an inviscid gas with small dust particles. Asymptotic analysis is used to derive the zeroth and the first order solutions and it is generalised to all geometries, i.e., planar, cylindrical and spherical. The forms of drag force and the heat transfer rate experienced by the particles not in equilibrium with the gas are derived. The decaying characteristics of blast waves along with the enhancements in decay caused by varying the quantity of dust are investigated.

含尘气体中爆炸波衰减的分析

在本文中，研究了在具有小尘埃颗粒的不粘气体的两相非定常流动中尘埃颗粒对爆炸波衰减的影响。渐近分析用于导出零阶和一阶解，并且将其推广到所有几何形状，即平面，圆柱和球形。得出了与气体不平衡的颗粒所经历的阻力形式和传热速率。研究了爆炸波的衰减特性以及由于尘埃量的变化而引起的衰减的增强。
