Biglobal resolvent analysis of separated flow over a NACA0012 airfoil
Journal of Fluid MechanicsThe effects of Reynolds number across ${\textit{Re}}=1000$ , $2500$ , $5000$ and $10\,000$ on separated flow over a two-dimensional NACA0012 airfoil at an angle of attack of $\alpha =14^\circ$ are investigated through biglobal resolvent ...

Spatially resolved atomic absorption analysis
Journal of Analytical Atomic Spectrometry, 2000Previous research carried out in our laboratories has shown that all the key parameters of electrothermal atomic absorption spectrometry, gas phase temperature, intensity of the probing beam and number density of absorbing species, are generally highly non-uniform over the absorption volume. Further, it was shown that, when using conventional detection

Eddy-viscosity-improved resolvent analysis of compressible turbulent boundary layers
Journal of Fluid MechanicsAn improved resolvent analysis is proposed in the regime of compressible turbulent boundary layers. To better model nonlinear processes in the input, the resolvent framework is augmented by adding eddy viscosity.

Stellarator magnetic analysis: resolvability problems
Plasma Physics and Controlled Fusion, 2001In all probability the only way to understand the theoretical possibilities and limitations of magnetic analysis is the use of a trial-and-error method. To demonstrate this, a virgin field of rigorous mathematical foundations of a three-dimensional (3D) equilibrium problem is briefly presented.

Laminar Separation Control for Eppler 387 Airfoil Based on Resolvent Analysis
AIAA JournalBy actively controlling laminar separation, the aerodynamic loading can be increased. In the context of turbomachinery, an increased loading allows for more power to be extracted or for a lower part count.

Data-Driven Resolvent Analysis
2020Benjamin Herrmann describes a data-driven algorithm to perform resolvent analysis from fluid mechanics to obtain the leading forcing and response modes, without recourse to the governing equations, but instead based on snapshots of the transient evolution of linearly stable flows.

Resolvent Analysis for Subsonic Compressor with Impedance Boundary Condition Casing Treatment
Journal of turbomachineryA resolvent analysis framework for the axial compressor was established, and the impedance optimization was achieved based on the resolvent analysis framework for the impedance boundary condition casing treatment. This framework was derived by treating
