Influence of axial water jet size on RVR mitigation in draft tube of Francis turbine

نویسندگان

چکیده

Abstract The present work investigates the effect of axial water jet nozzle size on unsteady pressure fluctuations arising from RVR formation in draft tube a Francis turbine operating at part load. results compare two different diameter jets for their pulsations and recovery tube. Simulations were carried out four injections varying 2% to 10% main discharge. study also presents changes net effective area average swirl with introduction jet.

Numerical Study of a Pipe Extension Effect in Draft Tube on Hydraulic Turbine Performance

Draft tube of Francis type hydraulic turbine usually consists of: cone, elbow and diffuser. On the contrary, in some power stations an extra pipe should be added to the draft tube at the bottom of cone because of installation limitation. In this paper, this special case has been numerically studied. To this end CFD analysis was applied to simulate all parts of hydraulic turbine. A homogeneous m...

Detecting Nonlinearity in Pressure Data inside the Draft Tube of a Real Francis Turbine

A general method for testing nonlinearity in time series is described and applied to measurements of different pressure data inside the draft tube surge of a real Francis turbine. Comparing the current original time series to an ensemble of surrogates time series, suitably constructed to mimic the linear properties of the original one, we was able to distinguish a linear stochastic from a nonli...

On the sloshing free surface in the draft tube cone of a Francis turbine operating in synchronous condenser mode

Hydropower plants may be required to operate in synchronous condenser mode in order to supply reactive power to the grid for compensating the fluctuations introduced by the intermittent renewable energies such wind and solar. When operating in this mode, the tail water in the Francis turbine or pump-turbine is depressed below the runner by injecting pressurized air in order to spin in air to re...

the influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry

بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
