A FIRST-ORDER MAGNETOHYDRODYNAMIC STOKES FLOW
Technical Report
·
OSTI ID:4797652
The first-order magnetohydrodynamic (MHD) flow of an incompressible conductive fluid about a small rigid sphere moving slowly in the direction of a uniform magnetic field was calculated. A perturbation stream-function was computed from the zero-order velocity and magnetic fields for use in evaluating the increase in drag due to the interaction between the two fields. The drag increase is proportional to the square of the Hartmann number and is a simple multiple of the Stokes drag value. Though the analysis is limited to very low Hartmann numbers, extension of the method to higher magnetic fields and to similar axisymmetric MHD problems is discussed. (auth)
