VELOCITY STRUCTURE OF FLOWS IN NONUNIFORM CONSTANT MAGNETIC FIELDS - 1. NUMERICAL CALCULATIONS.

Numerical calculations of the flow of a conducting fluid in a rectangular tube in nonuniform magnetic fields are presented. The results indicate the possibility, in principle, of realizing steady-state velocity structures of a most unusual kind in the flow. However, the quantitative estimate of the velocity distribution parameters depends very significantly on the difference scheme selected, the accuracy of the calculation, and the nature of assumptions about the magnetic field distribution.
