Abstract

The axisymmetric far turbulent wake in a perfect gas is considered. An integral method of computing both the first moments of the hydrodynamic fields and the turbulence intensity and the root-mean-square values of the enthalpy pulsations is proposed in Section 1. (The whole system of equations is closed by using semiempirical hypotheses.) Under the assumption of no inviscid gradients, an approximate analytical solution of the problem is obtained in Section 2, and asymptotic expressions (as x→∞) are presented for all the designated quantities. Numerical values of the experimental constants are estimated in Section 3 by comparing the computation with known experimental results.
