Theoretical analysis of annular laminar flows with MHD interaction driven by rotating co‐axial cylinder

Published: 22 April 2021 Publication History

Abstract

Theoretical solution is derived for annular laminar flows with MHD interaction driven by a rotating co‐axial cylinder. The effects on the flow field and rotational torque are clarified by changing the radius ratio and the strength of MHD interaction. As the radius ratio increases, azimuthal flow velocity increases and approaches the plane Couette flow profile for weak MHD interaction. The azimuthal flow velocity, however, decreases as the MHD interaction increases, and the reverse flow emerges in large radial locations. As the MHD interaction increases, the rotational torque increases. A larger radius ratio leads to the larger sensitivity of the change in rotational torque.
