On the calculation of interaction two-dimensional between a cloud of space dust particles and the atmosphere

The gas dynamics of intensive interaction between a cloud of space dust particles and the atmosphere is considered in two-dimensional axially symmetric formulation. The algorithm developed for the numerical solution of the problem is based on the use of an unstructured grid with separation of the key boundaries. An example of a solution is presented for the entry of a cloud of particles into the atmosphere with the kinetic energy characteristic of the Tunguska space body.
