The concept of rapid distortion is used to simplify the Reynolds stress closure equations. A solution for axisymmetric contracting turbulent flow is obtained and compared with the results of the rapid distortion theory of Batchelor and Proudman. The fluctuation ratio u¯2¯/v2¯now predicted compares favorably with the experimental data of Uberoi. The irreversibility of rapid distortion is discussed in view of experimental evidence.
