Abstract Utilization of hydro-power as a renewable energy source is now of prime importance in the world. Hydropower energy is available in abundance as a renewable source. For run-of river, low head reaction type Kaplan turbines mostly used. In this paper, a parametric study has been conducted on a complex geometry of Kaplan blade through static and dynamic computational analysis by varying the blade profile at different angles in the CAD model. Blade geometry surface and design were developed in Creo using the coordinate point system on the blade. Further blade profiles were analyzed to check and compare the output results. Results show that by changing the blade profile geometry, CAD models can be improved using the computational techniques. Consequences obtained were validated with the experimental/operational data and then four different blade profiles were developed. Research consequences showed improvement in the power output of the turbine.

改变叶片轮廓的 Kaplan 涡轮静力和动态计算分析

摘要 水电作为一种可再生能源的利用现在在世界上具有重要意义。水能作为一种可再生能源有丰富的可利用性。对于径流，主要使用低水头反作用式卡普兰涡轮机。在本文中，通过改变 CAD 模型中不同角度的叶片轮廓，通过静态和动态计算分析，对 Kaplan 叶片的复杂几何形状进行了参数研究。叶片几何表面和设计是在 Creo 中使用叶片上的坐标点系统开发的。进一步分析叶片轮廓以检查和比较输出结果。结果表明，通过改变叶片轮廓几何形状，可以使用计算技术改进 CAD 模型。获得的结果通过实验/操作数据进行验证，然后开发了四种不同的叶片轮廓。研究结果表明涡轮机的功率输出有所提高。
