## Appendix A: on Zeldovich's analysis of Taylor's resultsZeldovich (1981) had a similar goal in mind when he analyzed the results of Taylor's experiment. But he started from the idea that the turbulent flow was governed by the epicyclic frequency and the turnover frequency , where since they measure respectively the stability of the flow and the
strength of the shear. He defines a non-dimensional parameter
, akin to the Richardson number used
in stratified shear flow, and he seeks the confirmation of his
intuition that His best fit yields . However these profiles are contaminated by the Ekman circulation mentioned above, and they differ marquedly from those obtained by Wendt. A consequence of this constant a property which is not substantiated by the combined results of Taylor and Wendt, as can be seen in Fig. 2. © European Southern Observatory (ESO) 1999 Online publication: June 30, 1999 |
