摘要
Abstract
A compressible multiphase flow numerical scheme,induced from the multi-component diffuse interface model with arbitrary number of materials,is established to simulate the interaction between distinct materials under extreme conditions.A robust,low dissipation and high efficiency reconstruction method,the MTBVD(muscl thinc boundary variation diminishing),is proposed with the aid of artificial intelligence technology,which can adaptively select the most suitable reconstruction method in the essential regions such as shock wave,contact discontinuity and material interface,and can achieve the minimum global numerical dissipation.Furthermore,it has a higher computational efficiency than the traditional BVD(boundary variation diminishing)scheme.The automatic geometric modeling and grid meshing based on global geographic information system,adaptive mesh refinement and large-scale parallel computing method are established to realize the whole numerical simulation of shock wave propagation in complex terrain and real urban environments.Our schemes allows for the effective simulation of intense blast wave scenarios on a large scale within intricate urban settings,employing billions of meshes,a pressure spectrum ranging from 103 Pa to 1015 Pa,and a minimum spacing size of 10 km.We have conducted multiple numerical simulations that demonstrate the propagation of blast waves through complex landscapes and urban areas,which corroborate our methodologies.关键词
