摘要
本文将利用RNG k-ε湍流模型对轴流式模型水轮机进行了全流道三维非定常湍流计算,预测模型水轮机的压力脉动性能.同时,本文对轴流式模型水轮机进行了压力脉动试验,通过对模型水轮机压力脉动试验结果与数值计算结果的对比.以验证数值计算预测压力脉动性能的准确性和可行性。
Three-dimensional unsteady simulation using RNG κ-ε turbulence model was used in full flow passage of model Kaplan turbine. Then the pressure pulsation was obtained. Monitoring data of pressure pulsation in the turbine was obtained through experiment and was compared with the numerical simulation. And a good coherence was shown between the simulation and the experiment. Then the regularity of the pressure pulsation＇s distribution and transmission in the turbine was discussed in detail.
