Design of HAWT Rotor for Non‐Uniform Inflow Conditions: A Theoretical and Experimental Approach for Shear Flow

Energy Science &Engineering, EarlyView.
This paper aims to provide a robust design approach for HAWTs operating in shear flow. This study fills a critical research gap by integrating BEM and vortex theories for blade design in non‐homogeneous inflow conditions. The authors of the paper made an effort to develop and test an experimentally unsophisticated model of a turbine working in shear ...

Hierarchical Differentiable Fluid Simulation

Computer Graphics Forum, EarlyView.
We introduce a two‐step algorithm that significantly reduces memory usage for solving control problems using differentiable fluid simulation techniques: our method first optimizes for bulk forces at reduced resolution, then refines local details over sub‐domains while maintaining differentiability. In trading runtime for memory, it enables optimization

A Degradable Bioinspired Flier with Aerogel‐Based Colorimetric Sensors for Environmental Monitoring

Advanced Science, Volume 13, Issue 15, 13 March 2026.
Biodegradable fliers are developed inspired by Tipuana tipu samaras, integrating cellulose nanocrystal aerogel (CNCa) sensors loaded with natural dyes for pH and ammonia detection. The lightweight, degradable fliers mimic natural morphology and aerodynamics, offering an eco‐friendly, scalable solution for in situ environmental monitoring after passive ...

Progressive construction of a parametric reduced-order model for PDE-constrained optimization [PDF]

, 2014
An adaptive approach to using reduced-order models as surrogates in PDE-constrained optimization is introduced that breaks the traditional offline-online framework of model order reduction.

Numerical Investigation of Transonic Axial Compressor Rotor With Leading‐Edge Tubercles

Engineering Reports, Volume 8, Issue 3, March 2026.
Amplitude, wavelength, and span‐wise location of the leading‐edge tubercles on a transonic NASA Rotor 37 compressor are numerically optimized. An increase in efficiency by 0.52% compared to the corresponding baseline rotor is observed. The location of the shockwave moves downstream of the rotor with 1.91% higher pressure.
