文摘This paper presents the results of a numerical calculation on the meanbehavior of finite length line buoyant jets from slot with width B , discharged perpendicularly intorelatively deep cross-flows in the mixing region. The length of diffuser was varied from 4 to 20times the width of diffuser. The calculations were performed with the standard K-ε model and HybridFinite Analytic Method (HFAM) with staggered grid. The phenomenon and development of vortex pairsare simulated successfully and the influence of diffuser length and buoyant on turbulent buoyantjets are analyzed.
