Abstract

The comparison of two Eulerian methods for simulating low inertia particle flows in a moving gas is performed for the case of hyperbolic flow. The traditional Lagrangian approach is used as a reference. It is shown that for low inertia particles, results obtained by the two-fluid Eulerian approach and the Lagrangian approach are in a good agreement. For the Eulerian equilibrium approach a reasonable agreement with the Lagrangian approach is achieved only for very small particle response time values. The discrepancy increases significantly with the growth of the particle response time.
