Experimental study on the behavior of horizontal turbulent side jets in compound open channel with vegetated plain

  • The Micro ADV is used to test the round jets in the cross flow in the unsymmetrical compound channel with vege tated plain for the 3 typical cross sections.The measured velocity fields show that the interact ion between the jets and the cross flow results in bifurcation,which is enlarged by the secondary flow and allayed by vegetation.The half angle of the bifurcation is 5.71°.The velocity and the turbulent kinetic energy of the jet exit plane with different jet-to-cross velocity ratios are obtained.It is found that the jets are anisotropic in the whole flow field.The curvature of the jet curve and the jet center lines's location mainly depend on the jet to cross velocity ratios.The data can be used to validate the turbulent model and the numerical methods.
