摘要
根据流体力学的基本方程 ,考虑引起烟气抬升不同阶段的掺混原因 ,将产生的掺混率叠加导出一个简单的掺混函数 ,从而得到一个计算烟气抬升运动的积分模型 。
The model is based on differential equations for the conservation of mass,momentum,concentration and thermal energy.The entrainment model is applied to the different rise stages.It is assumed that the entrainment rate can be obtained as a sum of terms representing near field entrainment of a buoyant jet and far field mixing due to ambient turbulence.The predicted trajectories are compared with experimental results.
