A Sequential Quadratic Numerical Optimization Technique to Compute Critical Flutter Speeds

International Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.
ABSTRACT A stable sequential quadratic numerical optimization technique is proposed to compute critical flutter speeds without resorting to complex algebra. The solution of the traditional eigenproblem stated in the frequency domain, and whose complex conjugate eigenvalues provide insights on the stability of the dynamic aeroelastic response, is ...

A Review of Flow Field and Heat Transfer Characteristics of Jet Impingement From Special‐Shaped Holes

Engineering Reports, Volume 8, Issue 9, September 2026.
Special‐shaped nozzles and nanofluid integration enhance jet impingement cooling by improving heat transfer and thermal uniformity. However, gains are constrained by increased pressure drop and stability challenges, highlighting the need for optimized designs and multiscale modeling to achieve efficient, scalable thermal management.

Notes on Airfoil Design [PDF]

, 1995
This report deals with airfoil design. Although the statements presented are quite general, particular attention has been given to the design of two dimensional airfoil sections for wind turbine rotor blades. Airfoil target charateristics obtained in a previous study on optimization of a 22 m wind turbine rotor has been used.

Biophysical structure and particle dynamics of an algal bloom within a mesoscale eddy

Limnology and Oceanography, Volume 71, Issue 9, September 2026.
Abstract Mesoscale eddies create dynamically distinct environments where thermohaline fronts partition the biological and optical structure of the upper water column. How these fronts organize the vertical and lateral structure of spring blooms is a longstanding observational challenge, largely because the bloom environment evolves rapidly across ...

Magnetic‑Field‑Assisted Thermoplastic Composite Shaping: Heat‐softened Volumetric Reconfiguration for Accelerated Manufacturing

Macromolecular Materials and Engineering, Volume 311, Issue 9, September 2026.
ABSTRACT Additive manufacturing (AM) of multifunctional thermoplastic composites faces persistent trade‑offs among speed, geometric complexity, and property control. Volumetric AM (VAM) of composites, relying on beam‑based volumetric photopolymerization, is an emerging manufacturing with the potential to revolutionize all parts manufacturing; however ...
