In this paper, supersonic dusty shock-layer flow over a blunt body is numerically studied by the Eulerian and Lagrangian hybrid approach. For the gas phase, the axisymmetric Navier-Stokes equations are solved by the finite difference method, while the particle phase is analyzed by the method of particle tracing. The bounce of particles at the body surface is considered. The gas-particle interaction is taken into account by evaluating the momentum and energy exchange between the particle and the ambient fluid. The numerical results show that the presence of particles in the flow causes the reduction in the shock-layer thickness and the augmentation of the wall pressure and wall heating rate. These effects strongly depend on the size of the particles.
