Numerical analysis of turbulent flow in momentumless wakes behind the sphere and the prolate body of revolution in homogeneous and linearly stratified fluids was carried out. The results of numerical investigation based on modern turbulence models of second and third orders with known theoretical and experimental data are consistent. We showed proximity of these currents on some properties including self-similar decay of turbulence in a far wake in a homogeneous medium and the relationship between the second and third invariants of the reynolds stress tensor. We also considered the problem of interaction between the two turbulized regions generated by the motion of the sphere and the prolate body in a homogeneous medium.
