Single-point method of identification of magneto-hydrodynamic discontinuities
- 23 Downloads
For each type of discotinuity the magneto-hydrodynamic relationships are reduced to a set of necessary relations between the parameters at both sides of the shock. The relations which do not contain the pressure are used in the method proposed. The distance in the space of the parameters between the point corresponding to the experimental data and the nearest point exactly satisfying the relations is obtained for each case. Supposition is made that the shortest distance conforms to the most probable type of discontinuity.
As an illustration of the proposed method several events of discontinuities experimentally registered in the interplanetary space are considered.
