This research examines two-dimensional particle-laden flow using computational approaches. The analysis focuses on the impact of the dust particle seeding on the viscous flow of compressible gas. Multiphase flows in the supersonic region can now be solved using a newly built solver. Very little is known about supersonic dusty gas flows, and the vast majority of the literature focuses on flows with low Mach numbers. In this work, the impact of varying particle sizes on flow along a cylinder is examined within the context of a supersonic flow. The simulation findings show that particle seeding in the flow causes disturbances. According to the research, when particles are of the same size and provide the same volume fraction to a supersonic flow, the flow becomes more unstable, but the cylinder experiences greater drag.

摘要

This research examines two-dimensional particle-laden flow using computational approaches. The analysis focuses on the impact of the dust particle seeding on the viscous flow of compressible gas. Multiphase flows in the supersonic region can now be solved using a newly built solver. Very little is known about supersonic dusty gas flows, and the vast majority of the literature focuses on flows with low Mach numbers. In this work, the impact of varying particle sizes on flow along a cylinder is examined within the context of a supersonic flow. The simulation findings show that particle seeding in the flow causes disturbances. According to the research, when particles are of the same size and provide the same volume fraction to a supersonic flow, the flow becomes more unstable, but the cylinder experiences greater drag.
