The Effects of Particles Momentum Transfer in Shock Wave/Boundary Layer Interaction
Abstract
Numerical simulations of solid particles seeded into a supersonic flow containing an oblique shockwave reflection were performed in order to observe and understand the momentum transfer effects between solid and gas phases in shock-wave / boundary layer interaction. Particle size and mass loading were varied to study the problem. It was found that solid particles were capable of significant modulation of the flow field as the separation bubble was suppressed primarily by the additional momentum introduced by the particles into the flow field. The particle size controlled the rate of momentum transfer while the particle mass loading controlled the magnitude of momentum transfer. As particles are seeded into the flow, a flow transition to unsteady, three-dimensional flow is observed in the simulations. The seeding of micro and nano-particle upstream of a supersonic air-breathing propulsion system as a flow control concept is proposed.
