Extract

Screens and contraction are used to achieve a low level of free-stream turbulence in the test-section of a wind tunnel. The effect of contraction on turbulence was initially studied, theoretically, by Prandtl, Taylor, Ribner and Tucker and Batchelor and Proudman. The last two theories, called rapid distortion theory, take into account the random nature of turbulence, but assume that the turbulence is initially isotropic, the effect of viscosity is small and the distortion is rapid.
