updated on 3/7/2018. % % % % Remark: % % y/delta : Grid point in wall-normal direction, Normalized by channel half width % y^+ : Grid point in wall-normal direction % U : Mean profile of streamwise velocity % dU/dy : Derivative of U in wall-normal direction % W : Mean profile of spanwise velocity % P : Mean profile of pressure % % * Data at y/delta = 1.0 is not computed due to code performance optimization % % ** W should be zero due to (statistical) symmetries in the flow. % It is reported here none-the-less as an indicator of the quality of the statistics. % % -----------End of
