The linearity principle of scalar transport, proposed by Pope (Phys. Fluids 1983), has long been ignored in existing models. An examination of existing scalar transport models indicates that some of the terms employed do not satisfy the principle. We propose a new model which satisfies the linearity principle and takes into account the effect of the Prandtl number. The model is applied to scalar transport in a turbulent channel flow for Pr=0.71 and 0.025. The results obtained are in good agreement with DN S data.
