The paper “Biorthogonal stretching of an elastic membrane beneath a uniformly rotating fluid“, co-authored by Matt Turner and Patrick Weidman (University of Colorado), has been accepted for publication in Physical Review Fluids. The paper identifies exact solutions of the Navier-Stokes equations when a stretching surface is placed below a uniformly rotating layer of fluid. Two branches of solutions are identified for a given rotation rate, and stretching rates in the x and y-directions, one stable and one unstable. The author final copy of the paper can be found here.
