HYDROMAGNETIC EFFECTS ON INTERNAL FLOW SEPARATION IN A DIVERGING CHANNEL

摘要

In this paper, we presented the computed results for the effects of an externally applied homogeneous magnetic field on the development of internal flow separation in a two-dimensional symmetrical channel with walls parallel upstream but not parallel elsewhere. The particular example studied most fully is that of gradual exponentially diverging channel. The solution for the flow governing non-linear equation is found using perturbation method together with Pade approximation technique. Our results reveal that internal flow separation development at moderately large Reynolds number is suppressed by an increase in magnetic field intensity.
