Analysis on the effect of variable guide vane numbers on the performance of pump as turbine

Advances in Mechanical Engineering, 2018
To study the effects of different guide vane numbers on the unsteady performance of pump as turbine based on the Navier–Stokes equation and standard k-epsilon turbulence model, computation fluid dynamics technology was used to simulate the flow field in ...

A new method to identify and explain sources of precipitation modification, illustrated for the western Netherlands

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study develops a method to identify the source areas of precipitation events, as illustrated for the western part of the Netherlands. Radar‐based precipitation data are traced back to their source areas and machine‐learning techniques are used to identify hypothesized causes: urban heat, surface roughness, and air pollution. We find that urban and

Systematic analysis on the energy loss in pump-turbines

Advances in Mechanical Engineering
The pump-turbine is a key component in pumped-storage power stations, operating under complex conditions. RANS (Reynolds-Averaged Navier-Stokes) is commonly used for numerical simulations, but the differences among various RANS models under different ...

Trading Strategies on Local Electricity Markets Using Agent‐Based Modelling and Reinforcement Learning: Vectors to Expand Energy Communities

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Energy communities (ECs) members have a high degree of heterogeneity. Agent‐based modelling (ABM) allows for the modelling of each entity as an agent with distinct characteristics and decision rules. This is particularly useful when the heterogeneity of agents affects outcomes.
