| Abstract [eng] |
The electric power plays a significant role in the daily life of human beings. The power generating from fluid majorly water is also called as hydropower is one of the easiest and very renewable types of energy conversion. The hydraulic turbines convert the hydraulic energy obtained from the flow of water into mechanical energy; this received energy is converted into electrical energy with the help of electric power generators. The hydraulic turbines have the row of blades fitted to the rotor element flowing fluid passes through the hydraulic turbine strikes the blades of the turbine and allow the shaft to rotate. In this research, the underpressure helical turbine is considered. The underpressure helical turbine solves the problem of transformation of potential energy into kinetic energy in rotor sphere. The underpressure helical turbine rotor is performed like a vertical cylinder which has a spiral line executed by its external circumference and is centrally and spherically movable placed inside of the casing. This research evaluates the functional parameters such as hydraulic torque and hydraulic efficiency by varying the geometrical parameters such as diameter of the turbine rotor and pitch of the turbine blade. The geometrical model of the turbine is developed, and the analytical analysis results are obtained for the main functional parameters. The computational model is created for the numerical simulation of the turbine design and results are obtained by using SolidWorks-2018 software. The results are compared between the analytical analysis and numerical simulation to evaluate the functional parameters of the underpressure helical turbine. Hydraulic torque is the ability of turbine to produce the required torque by utilising the flow of water energy to rotate the electric power generator shaft generator. Hydraulic efficiency is the ratio of water power at the outlet to the water power at inlet of the turbine. |
