摘要 垂直轴水轮机由于自身结构决定,轮机转动一周过程中转速是不稳定的,为了研究转速波动对垂直轴水轮机性能的影响,采用耦合式方法对其进行数值模拟研究.采用一试验模型作为计算算例,对比叶轮角速度的计算结果和试验测量结果,计算结果和试验结果吻合较好.在此基础上并研究了转动惯量对水轮机转速波动的影响,研究发现:转动惯量较大时,采用非耦合方法与采用耦合方法计算结果相差不大;转动惯量越小,水轮机转速波动越大,越不利于轮机吸收能量. 垂直轴水轮机由于自身结构决定,轮机转动一周过程中转速是不稳定的,为了研究转速波动对垂直轴水轮机性能的影响,采用耦合式方法对其进行数值模拟研究.采用一试验模型作为计算算例,对比叶轮角速度的计算结果和试验测量结果,计算结果和试验结果吻合较好.在此基础上并研究了转动惯量对水轮机转速波动的影响,研究发现:转动惯量较大时,采用非耦合方法与采用耦合方法计算结果相差不大;转动惯量越小,水轮机转速波动越大,越不利于轮机吸收能量.
