Utility of CFD in the design and performance analysis of hydraulic
1. Introduction. Since 1827, there have been many innovations in the field of green energy like hydropower for enhanced harnessing through such abundant sources (Thapa et al., 2018).Hydropower as a clean and renewable energy has an important share in the world energy scenario (Wang et al., 2019) and contributes about 16.4% of the total Vol. 30 Issue 4, 2023. The water supply for hydropower plants in Switzerland, is predominantly sourced from gravel-rich mountain streams using Tyrolean weirs. However, to keep solids out of the turbine water system, a sand trap must be installed. Furthermore, the Tyrolean weir inhibits fish migration. For these reasons, Coanda screens areOptimised Coanda screen for hydropower and fish

Economic analysis of operation and maintenance costs of hydropower plants
The average O&M costs for Francis turbine-based hydropower plant is found to be about ₹2.346 million/MW/year, while for Kaplan turbine-based hydropower plant, it is found as about ₹4.192 million/MW/year. It means the maintenance costs of the Kaplan turbine-based hydropower plant is 78.68 % higher than the Francis turbine-based plants. ii)Until now, the company has installed hydropower plants with a maximum capacity of 49.9kW, and they are now working on a project with a maximum capacity of 420kW.

Water Free Full-Text Estimating Energy Efficient Design
Trash racks are usually composed of an array of bars installed in a hydropower scheme to safeguard the turbines by collecting water-borne detritus. However, current design approaches for the design of trash racks focus on structural criteria. A little attention renders the proper evaluation of hydraulic criteria, which causes a significant In order to increase the lifespan of hydraulic turbines in hydropower plants, it is necessary to minimize damages caused by sediment erosion. One solution is to reduce the amount of sediments by improving the design of sand trap. In the present work, the effects on sand trap efficiency by installing v-shaped rake structures for flow distribution Investigations of Rake and Rib Structures in Sand Traps to
