TAYLOR INSTABILITY OF MAGNETIC LIQUID FLOW IN AN AXIAL MAGNETIC FIELD
The results of investigation of the Taylor instability of magnetic liquid fl ow in a homogeneous magnetic fi eld between rotating cylinders in the narrow gap approximation are presented. It has been established that the nonisothermicity of fl ow leads to a substantial decrease in the instability threshold, as in an ordinary liquid. On the other hand, the infl uence of the magnetic fi eld is reduced to the instability threshold of an ordinary liquid by means of viscosity renormalization, i.e., the redetermination of viscosity in terms of anisotropic components. Apart from the results obtained, the work is of interest in the context of the methods of numerical solution of such class of problems.
