Heat and mass transfer on the surface streamlined by a high-temperature high-speed heterogeneous flow

摘要

By studying lows with a high concentration of particles, it was found that the heat flux and erosive mass ablation in the area of the critical point on the body surface immersed in flow are nonlinear functions of the flow density of particles interacting with the body which can be explained by the screening effect of the layers of particles ahead of the body. For simulating the interaction of heterogeneous flows with a surface, heterogeneous jets with a large concentration of particles were used. Some features of flow at different concentrations and sizes of particles are established.
