The effect of homogeneous and isotropic turbulence on a second order chemical reaction rate - Comparison between H. L. Toor's model and experimental observations

Experimental results involving the effects of turbulence created by a grating on the rate of conversion of methyl formiate through alkaline hydrolysis were compared with predictions for 2nd order chemical reaction rates modeled by Toor (1975). Concentrations of NaHO were measured by conductimetry at the entrance of the channel and the longitudinal evolution of reaction products were monitored down the channel. Curves which resulted showed good agreement with Toor's prediction for both fast and slow reactions. A correlation factor was developed to express the ratio of chemical components as following a law of decrease of concentration fluctuation variance by a passive scalar according to a Gaussian probability.
