Abstract

Second-order moments of the breakdown coefficients qr,l of the squared velocity derivative in plane and circular jets indicate a value of the exponent μ which is larger than that obtained by other methods using the same data or that previously reported by other workers using the same method on atmospheric data. The difference may be due to a failure of the present data to satisfy the first condition of scale similarity, possibly because of the relatively small Reynolds numbers of the laboratory flows. The dependence of the variance of ln qr,l on the length scale l appears to be independent of Reynolds number.
