Description
Summary:Low-order Galerkin computational results [Phys. Fluids 8, 1972 (1996)] predict a decrease of vortex shedding frequency f with increasing cylinder rotation angular velocity ω, in conflict with much earlier experimental results [M.S. thesis, University of California, San Diego, 1968; AIAA J. 7, 1817 (1969)] for which f increases with increasing ω. A possible flaw in the computations is noted, and a correlation of experimental and computational results is presented.
