You can also get detailed technical information from the Environment Agency to find out how you need to design and operate your hydropower scheme to protect the environment.
The Environment Agency is less likely to accept proposals in sites of high environmental sensitivity, like protected sites and sites where there are protected species. Depending on water flow micro hydropower design guideline design, Pelton wheels operate best with heads from 15 meters micro hydropower design guideline 1, meters, although there is no theoretical limit.
In this turbine, water is brought down through the penstock pipe to a nozzle, and it comes out into the turbine casing. The jet is then directed at a wheel, or runner, which has a micro hydropower design guideline of buckets around its edge.
The force of the jet on this wheel makes it turn and gives the output power [ 7 — 9 ]. However, investigation micro hydropower design guideline that there is no company or institution engaged in supplying this micro Pelton turbine locally in the country.
micro hydropower design guideline As a result, the necessity and the possibilities to design and manufacture Pelton turbines locally are increasing. More often the material and the skilled labour as well as technical staff are available but what is missing is the information and knows-how [ 46 ].
More precisely, in the new context where harvesting small hydro potentials can become economically viable, there is also a need to provide solutions to reduce the micro hydropower design guideline cycle time and cost for Pelton runners.

It is known that, with increasing demand, the performance analysis of turbine such as efficiency and dynamic behavior is also an important micro hydropower design guideline to analyze its suitability under different operating conditions [ 7 ].
Additionally, it is used by the turbine producer to guarantee the hydraulic performance of a turbine micro hydropower design guideline the customer. However, it is known that design of Pelton turbine is mainly conducted from know-how and extensive experimental testing, which provide an empirical understanding of factors that are important to turbine design.
Therefore, the incorporation of computational fluid dynamics CFD in the design of micro hydro turbines appears to be necessary in order to improve their efficiency and cost-effectiveness beyond the traditional design practices [ 710 — 12 ].

The main topic of investigations by the CFD method has focused on the interactions between the jet and the rotating buckets as well as the relative flows within the buckets. These are flows that are so far not easily accessible by experimental measurements [ 11 ].
CFD simulations are therefore likely considered as an available way for investigating complex flows in Pelton turbines, micro hydropower design guideline that they are reliable and able to reveal the possibility of improving the system efficiency and reducing the manufacturing micro hydropower design guideline.
In addition, CFD provide deeper understanding micro hydropower design guideline the flow mechanisms that govern performance. As explained by Zhang [ 7 ] in Pelton turbine book, hydraulic design of a Pelton turbine, the related practical experiences have thus always played a major role besides applying general design rules.
Even the optimum bucket number and the size of a Pelton wheel, for instance, were determined only by experience micro hydropower design guideline model tests without relying on any hydro mechanical background.
The main reasons for this were the complex flow conditions in both the high-speed jet and the unsteady interaction between the high-speed jet and the rotating Pelton micro hydropower design guideline [ 711 ]. The capability of solving complex impulse turbine related problems that include multiphase flow with free surfaces has been demonstrated by a number of studies and is becoming increasingly significant [ 10 — 18 ].
What is the difference between micro, mini and small hydro?
However, large computational micro hydropower design guideline of the simulations is also the main factor why there is a lack of publications on CFD usage for Pelton turbines [ 11 ]. He is, currently, working at Hydro-Solutions Pvt.
