text: Let  be the free stream velocity and let  be the spacing between a two-dimensional grid.  The velocity field  of the Kovaszany flow, expressed in the Cartesian coordinate system is given by
  where  is the root of the equation  in which  represents the Reynolds number of the flow. The root that describes the flow behind the two-dimensional grid is found to be
  The corresponding vorticity field  and the stream function  are given by
  Similar exact solutions, extending Kovasznay's, has been noted by Lin and Tobak and C. Y. Wang.
