The classical statistical diffusion theory and the binomial autocorrelation function are used to obtain a new formulation for the turbulence dissipation rate ε. The approach employs the Maclaurin series expansion of a logarithm function contained in the dispersion parameter formulation. The...

In this paper is evaluated the inertial subrange Kolmogorov constant C0 in a stable boundary-layer. The importance of the constant C0 is well known as predictions of turbulent dispersion by means of Lagrangian stochastic models depend upon its value. Different values of the C0 constant has been...

Considering the convective boundary layer physical structure and their characteristics, a derivation for the Lagrangian decorrelation timescales to be used in Lagrangian stochastic particle models has been developed. That is, expressions for the Lagrangian decorrelation timescales depending on...
