Design of Intelligent Control Law Embedded With Dynamic Flow Field Perception Method for High‐Angle‐of‐Attack Maneuvers of Numerical Virtual Flight Agent

International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
In numerical virtual flight (NVF) tasks, strong unsteady flow disturbances can change aerodynamic behavior and reduce the effectiveness of control surfaces, increase the difficulty of aerodynamics modeling and controlling at high‐angle‐of‐attack (high‐AoA).

Proposal of a Parameterized Methodology for the Hydrodynamic Design of High‐Efficiency Pelton Rotors Validated by Multiphase CFD Simulations

International Journal of Rotating Machinery, Volume 2026, Issue 1, 2026.
This work presents and validates a direct analytical methodology for the parametric hydrodynamic design of Pelton rotors. The proposed approach combines a one‐dimensional theoretical framework for defining global geometric rotor parameters with an inductive method for generating bucket geometry, formalized from a comprehensive mapping of a high ...

Optimizing a Straight‐Bladed Vertical Axis Wind Turbine With Computational Fluid Dynamics (CFD), Artificial Neural Network (ANN), and Genetic Algorithm (GA)

Energy Science &Engineering, Volume 13, Issue 12, Page 6003-6016, December 2025.
ABSTRACT Vertical axis wind turbine (VAWT) is a suitable renewable power generation tool for use in urban areas, especially at low wind speeds and with low noise level. However, an approach with accurate results, acceptable time consumption, and cost for optimizing this turbine is not reported in the literature.
