摘要
为探讨倾斜角对立式循环撞击流反应器(VCISR)混合性能和桨叶受力的影响规律,采用数值方法分别模拟了四种倾斜角下对反应器内流速和桨叶受力情况,并展开了对比分析,将桨叶倾斜角θ分别设置为15°、30°、45°、60°.结果表明,当θ=45°时,反应器内的混合性能最佳;工质的循环能力最强;上下桨叶受到的合力最小;桨叶绕Z轴旋转的合力矩最小,该结果为立式撞击流反应器的桨叶的倾斜角优化设计提供理论参考依据.
In order to explore the influence rules of the mixed performance and the forced blades under different inclinations,the numerical simulation method was employed to simulate the force analysis of blades and speed in the reactor under four various inclinations in this paper.The inclinations of the blades θ were set as 15°、30°、45°、60°,respectively.The results were obtain through the comparative analysis for four different conditions.The results showed that,when θ=45°,the mixed performance of the reactor and the cycle capability of the intermittent were optimum as well as the resultant force of the fluctuation blades and the resultant moment of force of the blades rotating along Z axis were the minimum.This conclusions provided the theoretical references for the optimization design of the blades in the VCISR.
