Absolute versus convective helical magnetorotational instabilities in Taylor-Couette flows

Rainer Hollerbach, Nigel Sibanda, Eun-jin Kim

We study magnetic Taylor-Couette flow in a system having nondimensional radii $r_i=1$ and $r_o=2$, and periodic in the axial direction with wavelengths $h\ge 100$. The rotation rati…
