The measured values of for each turbulent motion remain almost unchanged in the radial direction, but in a strict sense, those for ejection and sweep changed trend around r/b = 1.0. This implies that the Fle-Wood s metal bubbling jet has two large-scale coherent structures, the boundary being located around r/by = 1.0. This result is consistent with the above-mentioned findings on the appearance frequency and the contributions of each turbulent motion to the turbulence kinetic energies and the Reynolds shear stress.
