Energy harvesting from hydroelectric systems for remote sensors [PDF]

open access: yes, 2016
Hydroelectric systems are well-known for large scale power generation. However, there are virtually no studies on energy harvesting with these systems to produce tens or hundreds of milliwatts.

Pregled dimenzioniranja Peltonove turbine

open access: yesZbornik radova, 2021
Unutar ovoga rada biti će dan pregled dimenzioniranja Peltonove turbine. Kako se pri radu turbine javljaju vrlo složeni uvjeti tečenja i fizikalni procesi, optimizacija i samo dimenzioniranje ovakvog sustava je izazov. Primjerice, u radu turbine javljaju se četiri režima tečenja: (i) stacionarno tečenje u uzvodnim i dovodnim cijevima, (ii) slobodni pad

Characterization of energy loss in jet mechanism of a Pelton turbine [PDF]

open access: yesInternational Journal of Fluid Engineering
Pelton turbines are becoming widely used in hydropower generation. However, the internal flow mechanism and energy loss characteristics of these turbines remain unclear, and there has been relatively little research in this area.

Numerical and Experimental Investigations of the Flow in a Stationary Pelton Bucket

open access: yesJournal of Fluid Science and Technology, 2009
A numerical code based on one of mesh-free particle methods, a Moving-Particle Semi-implicit (MPS) Method has been used for the simulation of free surface flows in a bucket of Pelton turbines so far.

A Numerical Analysis of Fluid Flow and Torque for Hydropower Pelton Turbine Performance Using Computational Fluid Dynamics

open access: yesInventions, 2022
The difficulty of delivering electrical power to rural areas motivated the researchers to explore more accessible power sources. Hydropower is considered a desirable option due to its sustainability and lower costs.

Pelton turbine:identifying the optimum number of buckets using CFD [PDF]

open access: yes, 2016
A numerical case study on identifying the optimum number of buckets for a Pelton turbine is presented. Three parameters: number of buckets, bucket radial position and bucket angular position are grouped since they are found to be interrelated.

Smoothed particle hydrodynamics simulation of a laser pulse impact onto a liquid metal droplet. [PDF]

open access: yesPLoS One, 2018
The impact of a laser pulse onto a liquid metal droplet is numerically investigated by utilising a weakly compressible single phase model; the thermodynamic closure is achieved by the Tait equation of state (EoS) for the liquid metal.
