Development of a 1-D Performance Prediction Model for Pumps as Turbines
Proceedings, 2018 Pumps as turbines (PaTs) are becoming more and more attractive in Small Hydropower. PaTs are considered a cost-effective alternative to conventional turbines as long as their turbine characteristic curves can be predicted. Indeed, manufacturers need of a

Selection of Pumps as Turbines Substituting Pressure Reducing Valves
Procedia Engineering, 2017 Abstract Technical standards define operational limits for hydraulic parameters such as velocity or pressure. On this way, pressure control is a fundamental component for safe operation at water supply systems, mainly to reduce leakage, risk of disruptions and maintenance costs.

Reconciling Circular Economy and Net Zero: Firm Capabilities to Resolve Sustainability Tensions
British Journal of Management, EarlyView.Abstract Achieving net zero has become a key concern for firms to address climate change, yet growing evidence suggests that reducing reliance on fossil fuels for energy generation alone is insufficient. As material use is increasingly recognized as a significant source of greenhouse gas emissions, the circular economy has emerged as a potential ...

RELIABILITY OF THERMO-MECHANICAL EQUIPMENT IN POWER PLANTS – ELEMENTS WITH HIGH FAILURE R [PDF]
Analele Universităţii "Constantin Brâncuşi" din Târgu Jiu: Seria Inginerie, 2019 Thermal power plants are complex systems with many inter-dependence links and several critical elements that condition the operation of the whole plant. Failure of critical elements such as feed water pump results in a general shut down of the whole unit.
