49. s is the frequency of the surface renewals and a is the constant determined by the experiments. In the correlation, a is used as the parameter for the calibration. The scalar transfer experiments by Komori et al. show that the parameter a is approximately 0.34 for wide range of the Reynolds number in the open-channel flows. If the surface-renewal process is not intermittent but continuous, the total patch area in the Rashidi et al. correlation and the calibration parameter a in the Komori et al. correlation should be 1. These parametrizations can be understood as the calibration for the intermittency of the surface-renewal.
