摘要
本文将双流体紊流模型推广应用于紊浮力回流的温差异重流.在应用中对两相连续性方程的源项进行了完善;在求解方法上用总体连续性方程建立压力修正方程,并建立了由无滑移单流体模型过渡到双流体模型的数值解法.本文的计算结果与一组实测资料进行了对比,两者符合较好.
The two-fluid-mod.el of turbulence is applied to density current in turbulent buoyant recirculating flows with the improvement of source terms in the phase continuity equations, and with the advancement of a numerical method which approaches the two-fluid system from a no-slip one-fuid system and builds the pressure correction equation in the basis of mixture continuity equation. The calculation results of one working condition are in good agreement with the experimental data.
