  rapid distortion
However, the effects of the additional rapid distortion and return to isotropy terms on the formula are negligible when compared with the use of the simple return to isotropy term proposed by Rotta.
      
The importance of including additional terms for rapid distortion and return to isotropy in the modeling of the pressure-strain correlation in turbulent shear flows under the influence of external body forces is examined.
      
The effect of acceleration appears to be (at least qualitatively) of the same kind as is observed when turbulence is subjected to rapid distortion.
      
Interaction between the turbulence and the wave-induced air disturbances is treated by use of the mass and momentum conservation equations and the rapid distortion assumption.
      
Using the tools of large-eddy simulation (LES), rapid distortion theory andEulerian kinematic simulation, two-point properties of turbulenceare studied.

In this paper the problem of homogeneous shearing turbulence approaching and passing an obstacle is studied by vorticity method and rapid distortion theory as well as a simple Reynolds stress model. The aim is to gain some insight into the effect of streamline curvature,initial anisotropy, upwind mean shear and relative strength of uniform mean shear on the turbulent structures over the obstacle. It is found that in the outer region of the obstacle the streamline curvature is of second order importance...

In this paper the problem of homogeneous shearing turbulence approaching and passing an obstacle is studied by vorticity method and rapid distortion theory as well as a simple Reynolds stress model. The aim is to gain some insight into the effect of streamline curvature,initial anisotropy, upwind mean shear and relative strength of uniform mean shear on the turbulent structures over the obstacle. It is found that in the outer region of the obstacle the streamline curvature is of second order importance compared with the effect of the irrotational flow field produced by the obstacle. It is also found that for shearing turbulence passing the obstacle the pre-existing shearing motion would have significant effect on the turbulent structures. Comparing the changes in the equation for Reynolds normal stresses derived by rapid distortion theory with that derived by Reynolds stress model with the pressure strain terms of Launder, Reece and Rodi form, the two results agree approximately only when the initial turbulence is isotropic and the upwind mean shear is small.
