Flow Analysis Inside a Pelton Turbine Bucket [PDF]
Journal of Turbomachinery, 2006 The aim of this work is to provide a detailed experimental and numerical analysis of the flow in a fixed bucket of a Pelton turbine. The head, jet incidence, and flow rate have been varied to cover a wide range of the turbine functioning points. The experimental analysis provides measurements of pressure and torque as well as flow visualization.

Investigating the potential for using a simple water reaction turbine for power production from low head hydro resources [PDF]
, 2013 In this analysis the simple reaction water turbine known as Barker’s Mill is revisited. The major geometrical and operational parameters have been identified and, using principles of conservation of mass, momentum and energy, the governing equations have

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 6, June 2024.Abstract To help meet emission standards, hydrogen sulfide (H2S) from geothermal production may be injected back into the subsurface, where basalt offers, in theory, the capacity to mineralize H2S into pyrite. Ensuring the viability of this pollution mitigation technology requires information on how much H2S is mineralized, at what rate and where.

Importance of Variable Turbine Efficiency in Run‐Of‐River Hydropower Design Under Deep Uncertainty
Water Resources Research, Volume 60, Issue 6, June 2024.Abstract When less water is available, hydropower turbines are less efficient, or have to stop altogether. This reality is often neglected in recent work on the planning and operations of hydropower systems, despite widespread expected increases in drought intensity, frequency and duration.
