| Abstract | The runner of Minihydro system that designed by Electricity Generating Authority of Thailand (EGAT) has been used to produced the electricity. To analyze the performance and efficiency, also assess the possibility of using this runner in the bigger Minihydro system, the CFD calculation is using. The CFD calculation is performing by import the geometry data, which supplied by EGAT, into the ANSYS CFX CFD program. The boundary condition using in this calculation is mainly changing the inlet pressure value. After perform CFD calculation, these data will transfer into the FEA program, which is ANSYS Workbench, to analyze the structural strength of this runner in the recent operating condition. The results from CFD calculation have shown that this runner is operate lower than the optimal hydraulic efficiency, while results from FEA have shown that this runner can withstand the forces from the recent operating condition. To analyze the maximum performance and efficiency of this runner, the CFD calculation is performed by varying many conditions. First, the stator guide vane setting angle is changed. The results show that this change will increase the hydraulic efficiency of the runner when increase the angle. Second, the runner rotational speed is varying. The results have shown that this runner has the maximum hydraulic efficiency at the rotational speed lower than the recent condition. Finally, the material of the runner is substitute by others. The results also implied that the difference material with different fabrication process can be used in this system without reducing the structural strength of the runner. |
