基金项目: *国家自然科学基金

摘要: 本文针对稀相气固两相体系,选取双流体耦合模型,综合运用算子分裂技术和高精度高分辨率数值方法,研究了激波在粉尘气体中沿90°拐角的绕射特性,揭示了固相颗粒及其物性改变对激波绕射特征和波后流场结构的影响.

Abstract: In the present paper.a two-fluid model with interphase coupling effects is appliedto dilute gas-particle systems.In order to study,the characteristics of shock diffraction round a sharp 90 degree corner in the dusty gas,we adopt the operator-spliting technique and high-resolution numerical method,reveal the changes of diffraction pattern due to particle presence,and discuss the effects of particle properties onpost-shock flow field.
