Wing planform dependency on optimum supersonic airfoil

Nihon Kikai Gakkai ronbunshu, 2017
When a wing of airplane is designed, it is necessary to have knowledge regarding planforms considered their optimum airfoils in order to design efficiently, because each wing planform has both of advantage and disadvantage. In this study, the wing design

Multipoint Aerostructural Optimization of Wind Turbine Rotors Using a Coupled Blade‐Resolved Aerostructural Solver

Wind Energy, Volume 29, Issue 7, July 2026.
ABSTRACT Physics‐based design optimization workflows thread the needle between computational cost limitations and simulation complexity, often compromising between modeling detail and the range of operating design conditions. Multipoint aerostructural optimization of wind turbine rotors has so far been confined to low‐fidelity analyses or to high ...

Large airfoil models

Computers & Fluids
The development of a Large Airfoil Model (LAM), a transformative approach for answering technical questions on airfoil aerodynamics, requires a vast dataset and a model to leverage it. To build this foundation, a novel probabilistic machine learning approach, A Deep Airfoil Prediction Tool (ADAPT), has been developed.

Performance of PBF‐Printed Micro‐Channel Bipolar Plates as a Function of Flow‐Field Parameters and Plane Area

Fuel Cells, Volume 26, Issue 3, June 2026.
ABSTRACT SUS 316L bipolar plates (BPPs) with rectangular micro‐channels for polymer electrolyte membrane fuel cell (PEMFC) were fabricated using powder bed fusion (PBF) technology, and the effects of flow‐field structure parameters (channel width, rib width, and channel depth) on fuel cell performance were analyzed.
