%X Ambient turbulence has an important effect on plume rise. in this paper, considering the dissipation of plume momentum and buoyancy by ambient turbulence, we derive the governing equation of the bent-voer plume and give the trajectory equation and the final rise height formula of buoyant plume under neutral conditions. Near the stack, the trajectory equation is approximately the two-thirds law,whereas as the downwind distance becomes larger, the trajectory is depart from that the law appreciably and levels off gradually. Compared to the field experiments, this model simulates well the final rise as well as the trajectory of buoyant plumes.
