A mixed model for temperature structure functions in fully developed turbulent shear flows is constructed on the assumptions that the statistics of the energy dissipation rate ε is log-Poisson and the temperature dissipation rate N can be described by the β model. The temperature structure functions predicted by this mixed model are in excellent agreement with the experimental data reported in the literature.
