Abstract: To analyze the turbulent mixing, heat transfer or chemical reaction of multicomponent flow,it is essential to consider the fluctuation of scalar quantities such as concentrations, temperatures and so on.Based on the turbulent modeling theory,a model method is presented in this paper.Numerical calculations are conducted for a hot jet issuing into stagnant surrounding.The calculations, compared with the reported experimental data, show the satisfactory prediction of the temperature field.
