The paper “The steady flow of one uniformly rotating fluid layer above another immiscible uniformly rotating fluid layer” co-authored by Patrick Weidman (University of Colorado) and Matt Turner has been accepted for publication in Physical Review Fluids. The paper presents an exact solution to the axisymmetric Navier-Stokes equations for both co- and counter-rotating flows in the presence of a flat fluid interface. A schematic of the flow is shown left.  The final-form version of the paper can be found here.
