SUB-ALFVENIC INLET BOUNDARY CONDITIONS FOR AXISYMMETRIC MHD NOZZLES

37th AIAA Plasmadynamics and Lasers Conference, 2006
There are numerous electromagnetic accelerator concepts which require plasma expansion through a magnetic nozzle. If the inlet flow is slower than one or all of the outgoing characteristics, namely, the Alfven, slow and fast magnetosonic speeds, then the number of inlet conditions which could be arbitrarily specified are reduced by the number of ...

Numerical computations of internal flows for axisymmetric and two-dimensional nozzles

International Journal for Numerical Methods in Fluids, 1997
Summary: MacCormack's explicit time-marching scheme is used to solve the full unsteady Navier-Stokes, compressible equations for internal flows. The requirement of a very fine grid to capture shock as well as separated flows is circumvented by employing grid clustering.

Calculation of a two-phase flow in an axisymmetric nozzle

Journal of Engineering Physics, 1967
A system of differential equations is presented to describe a two-phase flow through an axisymmetric supersonic nozzle. The results for the solution of this system on a “Minsk-14” computer are given. The theoretical results are compared qualitatively with the experimental data.

Investigation of the solid impurity distribution in axisymmetric nozzles

Fluid Dynamics, 1975
Results are presented of an experimental investigation of the influence of the entrance conditions, the coarseness of the solid impurities (the nozzle scale), the profiles of the sub- and transonic parts of the nozzle, and the initial concentration on the discrete phase distribution in the exit sections of axisymmetric nozzles.
