Boundary value problems for the nonstationary Navier-Stokes equations treated by pseudo-differential methods.

MATHEMATICA SCANDINAVICA, 1991
Let \(\Omega\) be a bounded connected open set in \(\mathbb{R}^ n\) with smooth boundary \(\partial\Omega=\Gamma\) and denote by \(\vec u=(u_ 1,\dots,u_ n)\) the unit interior normal vector field defined near \(\Gamma\). Let \(I=(0,b)\), where \(b\in(0,\infty)\), let \(Q=\Omega\times I\), and let \(S=\Gamma\times I\). Denote \(f\mid_ \Gamma=\gamma_ 0 f\

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 ...
