Based on the theoretical equations of compressible particle-laden flow in multi-physical conditions,a MPI-Particle Solver based on dynamic linked list array is developed,which is coupled with a compressible flow solver of carried phase.The dispersed particle phase is different from the carried fluid phase,the previous one is based on the Lagrange coordinate system,while the later one is based on the Euler coordinate system.The traditional way is to use the global array to assign the memory to the dispersed particle phase to achieve the transfer between two-phase,but at expense of low computational efficiency.This paper uses dynamic linked list array to allocate memory to dispersed particle phase,achieve both problems.A series of DNS validations with references case have been done,in terms of multi-physical effects and two canonical cases at incompressible limit.
