Calculation of temperature field in the axis-symmetric jet at limited initial size

In this article we specified the semiempirical model for calculation of temperature field in axis symmetric turbulent current with any, but limited initial size. We have made numerical calculations by the integrated formula, which describes the experimental values with satisfactory accuracy. The formula is also suitable to determine the temperature fields in all the zone of current of round jet. Thus also empirical constants are used: the turbulent number of Prandtl and the parameter of exhibitor c=0.083 which shows, that the functions of required sizes distribution correspond to the normal low of distribution of mistakes and Gauss-type functions.
