Study on the Behavior of Bubbly Jest in Static Uniform Environment, 2, Numerical Study on the Behavior of the Zone of Flow Establishment and the Zone of Established Flow for Bubbly Jet

摘要: 采用气-液两相流两方程湍流模型,结合混合有限分析法,对静止环境中气泡射流进行数值模拟和分析。相对各种积分模型,这种模拟气泡射流的微分方程方法具有较强的预报性和普遍的适应性。数值计算结果与试验资料的较好吻合,从而验证了湍流模型和计算方法的有效性和正确性。

Abstract: A two-phase turbulence model and hybrid finite analytic method (HFAM) are used to predict the behavior of bubbly jet in static environment. It has more strong prediction ability than integral method relatively. The agreement between the calculated results and experimental ones show that the turbulence model and HFAM are effective and proper.
