Performance Evaluation of Pelton Turbine: A Review

Abstract

Earlier only experimental techniques were used to predict the performance of turbines. With advanced numerical techniques and increase in processing power of computers, Computational Fluid Dynamics (CFD) has emerged as an effective tool for the performance prediction of Pelton hydraulic turbine involving multi-fluid flow. Extensive work has been done for design optimization of reaction turbines using CFD. Now it is being extended for impulse turbines. The flow in reaction turbines involves only water as working medium, but in case of impulse turbines, water and air are working medium. The water jet issued from nozzle is surrounded by air and pressure around the jet and turbine is atmospheric. The performance of Pelton turbine depends upon the shape, size and quality of jet as well as shape of the buckets. In the present paper, the literature review on applications of CFD for performance prediction, design optimization of Pelton turbine have been discussed.DOI: http://dx.doi.org/10.3126/hn.v13i0.10042HYDRO NEPAL Journal of Water, Energy and EnvironmentIssue No. 13, July 2013Page: 28-35Uploaded date: 3/13/2014

Estudio Experimental Del Rendimiento De Una Turbina Pelton De Una Microcentral Para Distintas Condiciones De Operación

“…Next, we will present the equations used to calculate the power and performance of the turbine and the electric generator of the micro hydroelectric power station (Batbeleg & Lee, 2018;Cobb & Sharp, 2013;Gupta et al, 2014 The hydraulic power for an incompressible flow is defined: equation 1…”

“…Figure 3 shows the variation of the available head (inlet pressure) and the input power as a function of the water flow rate variation for injector openings of 25, 50, 75 and 100%. As the opening of the injector increases, the height decreases (or, for that matter, it increases as the injector closes), because the pressure drop decreases due to the increase in the area that gives way to the water flow rate (Gupta et al, 2014). The input power has a behavior similar to the height, this is due to Equation 1 The Figure 4 (right) and (left) show that the torque and the power of the shaft with respect to the speed of the turbine-generator shaft, have similar behavior, given Equation 2, they are practically linear with respect to the speed of rotation.…”

Modification, Simulation and Demonstration of Laboratory Scale Pelton Turbine for Waterfall Hydropower Plant

“…In all cases, every simulation requires a model. A model is a mathematical, logical or physical representation of a system entity, phenomenon or process [13,[21][22]. The advantages of model and simulation include less financial risk, repeatability against the same circumstances, examination of long-term impact, gain insight for process improvement, assess random variables, encourages in-depth thinking and understanding, and improvement of stakeholders" buy-in.…”

Experimental and Numerical Computational Fluid Dynamics Analysis on the Flow at Pelton Turbine Nozzle with Various Opening Settings

“…A nozzle transforms water under a high head into a powerful jet. The jet leaving the nozzle is surrounded by air [2]. The momentum of this jet is destroyed by striking the runner, which absorbs the resulting force.…”
