摘　　要：提出一种修正的均相流模型,即在模型的含气率守恒方程中引入气相水平滑移速度,该速度只存在于喷嘴附近的区域,其物理作用是将气体导入流体中.计算实践表明,修正的均相流模型能够解决侧吹装置中的气液两相流动问题.同水模型的实验观察比较表明,该模型模拟的气相分布特征同水模型观察结果符合较好.A new revised homogenous model is proposed to solve the problem about two phase flow in side blown reactor, in which the gas horizontal slip velocity is introduced in the gas conservation equation only in the injection zone, so as to make gas into bulk melt. The computed results show that the revised model can solve side blown problem reasonably and the computed gas distribution agrees very well with the experimental result.
