Simulation and Experimental Investigation of Low‐Speed Centrifugal Pump Coupled With Vertical Ultra‐Low‐Head Turbine for Small‐Scale Irrigation

Engineering Reports, Volume 8, Issue 3, March 2026.
From the reviews, a new concept of a low‐speed centrifugal pump (LSCP) driven by a vertical ultra‐low‐head hydro turbine (VULHT) was designed and tested on simulation and physical setup. It was performed with a 1.8 m delivery head, concluding as inefficient. For ultra‐low‐head conditions, different than centrifugal action is recommended.

High‐Fidelity Simulation‐Driven Control Framework for Robust Grid Integration of Renewable Energy Systems

Energy Science &Engineering, Volume 14, Issue 3, Page 1286-1299, March 2026.
This work proposes a high‐fidelity, simulation‐driven control framework for robust grid integration of hybrid PV–wind systems using a modular, hierarchical multi‐loop architecture with adaptive decision logic. The framework coordinates power, DC‐link voltage, and grid currents under fast load and generation changes, enabling safe exploration of extreme

Segmented Gurney Flaps for Improved Wind Turbine Wake Recovery

Wind Energy, Volume 29, Issue 3, March 2026.
ABSTRACT When wind passes through the rotor of a wind turbine, the velocity is decreased while turbulence is increased. The region of decreased wind speed behind the rotor is known as the wind turbine wake and is bounded by a complex structure of helical vortices. This structure occurs to be more stable in low ambient turbulence and low tip speed ratio
