Abstract

Numerical simulations were performed to study the fluid characteristics in a novel static jet mixer with respect to the specific configuration. The results show that the profiles of three velocity components are symmetry to the cross-section z/H=0.5 and varies with the same trend of the different radial position. The magnitude of tangential velocity is one order greater than that of the axial velocity. The baffle length has an effect on the velocity components. The peak of the turbulent intensity is always at the jet position and the trend is the same as that of the turbulent kinetic energy.
