The production of a ‘wake’ behind solid bodies has been treated by different authors. S. Goldstein ( 1 ) and S. H. Hollingdale ( 2 ) have discussed the laminar wake behind a flat plate, while the wake of a two-dimensional grid has been treated for the turbulent case alone using L. Prandtl's ‘Mischungsweg’ theory by E. Anderlik and Gran Olsson ( 3 ), ( 4 ).
L. I. G. Kovasznay (Thu,) studied this question.
