An Intermittency Model For Passive-Scalar Turbulence
Nianzheng Cao, Shiyi Chen
Abstract
A phenomenological model for the inertial range scaling of passive-scalar turbulence is developed based on a bivariate log-Poisson model. An analytical formula of the scaling exponent for three-dimensional passive-scalar turbulence is deduced. The predicted scaling exponents are compared with experimental measurements, showing good agreement.
