    "abstract": "Traditionally, trends of universal turbulence statistics are presented versus\nR-lambda, which is the Reynolds number based on Taylor\u0027s scale, lambda, and the\nroot-mean-squared (rms) velocity component, u\u0027. Taylor\u0027s scale and u\u0027, and\nhence R-lambda, do not have the attribute of universality. The ratio of rms\nfluid-particle acceleration to rms viscous acceleration is an alternative to\nR-lambda which has the advantage of being determined by the small scales of\nturbulence. This ratio, denoted R-a, has the following attributes: it is a\nReynolds number, it is composed of statistics of the small scales of\nturbulence, it can be evaluated with single-wire hot-wire anemometry, and like\nR-lambda, can be partially evaluated by means of flow similarity. For isotropic\nturbulence the relationship between R-a and R-lambda is shown. Velocity\nderivative flatness measured between counter-rotating blades appears monotonic\nwhen graphed versus R-a, unlike when graphed versus R-lambda.",
