Abstract Aiming at the problem of low production efficiency caused by unreasonable setting cutting parameters for CNC machining hydro-turbine runner blade, Force module VERICUT software is used to analyze and compare force, power, material removal rate blade under different parameters, find that can give full play capacity machine tool, use optimization function automatically adjust feed speed ...

Hydro-power plants are able to produce electrical energy in a sustainable way. A known format for producing is through generation scheduling, which task usually established as Unit Commitment problem. The challenge this process define the amount of that each turbine-generator needs deliver plant, fulfill requested dispatch commitment, while coping with operational restrictions. An optimal sched...

The TC 60 open flume propeller turbine is an example of a pico-hydro-based fluid engine. potential the can be maximized by paying attention to flow rate. This study aims analyze performance which influenced changes in discharge. method used descriptive analysis method. testing was carried out at CV Cihanjuang Inti Teknik laboratory Cimahi. Turbine begins making 9 discharge ranges from 1.28 litr...

Turbine wear caused by hydro-abrasion due to suspended sediment in the turbine water has a negative impact on power production and revenue of hydropower schemes. Efficiency desanding facilities that reduce load ahead turbines is key limiting hydro-abrasion. Existing built according common design approaches often show lack performance, particular under non-ideal site-specific inlet outlet condit...

This study presents a spatial analysis of physical and biotic river conditions below a low head hydro scheme in the River Goyt, UK. The overall aim was to assess whether changes in localized hydrological features, introduced by low head hydro, affect phytobenthic biomass. Single point and profile measurements of flow velocity and velocity vectors, elevation, depth and biofilm biomass were mappe...

Abstract The present study introduces the concept of mitigating pressure pulsations in a hydro-turbine draft tube. refers to using an adjustable guide vane system adjustability relates its ability rotate around axis. test rig for experimental is high-head Francis model turbine. Three sets vanes are distributed evenly circumferentially Each consists two hydrofoils. upper hydrofoil can move lower...

Vibrations of the basic assemblies hydrogen generator cause variable forces and loads that occurduring operation depending on operating mode. This paper presents some test results performed a Kaplanvertical type turbine. Measurements were at 3 measuring points (N1, N2 N3; Figure 1) using noncontactsensors, placed in pairs under 90 each point. Based measurements theanalysis obtained results, fol...
