Lift Coefficient Estimation for a Rapidly Pitching Airfoil
The error of lift coefficient estimates based only on a weighted-sum of the measured pressures are found to be noisy and biased, which leads to inaccurate estimates.

FiniteNet: A Fully Convolutional LSTM Network Architecture for Time-Dependent Partial Differential Equations
In this work, we present a machine learning approach for reducing the error when numerically solving time-dependent partial differential equations (PDE).
Enhancement of shock-capturing methods via machine learning
Because data can be used to learn nonlinear relationships, we train a neural network to improve the results of a fifth-order WENO method.
Near-surface dynamics of a gas bubble collapsing above a crevice
The impact of a collapsing gas bubble above rigid, notched walls is considered.

Simulation of humpback whale bubble-net feeding models
The acoustic wave behaviors in the spiral interior vary qualitatively with the vocalization frequency and net void fraction.

MFC: An open-source high-order multi-component, multi-phase, and multi-scale compressible flow solver
MFC is an open-source tool for solving multi-component, multi-phase, and bubbly compressible flows.

An assessment of multicomponent flow models and interface capturing schemes for spherical bubble dynamics
We demonstrate the inadequacy of the traditional 5-equation model of Allaire et al. [1] for spherical bubble collapse problems and explain the corresponding advantages of the augmented model of Kapila et al. [2] for representing this phenomenon.

Spectral analysis of jet turbulence
Over a range of low frequencies and the first few azimuthal mode numbers, these jets exhibit a low-rank response characterized by Kelvin-Helmholtz (KH) type wavepackets associated with the annular shear layer up to the end of the potential core and that are excited by forcing in the very-near-nozzle shear layer.

Spectral proper orthogonal decomposition and its relationship to dynamic mode decomposition and resolvent analysis
We also establish a relationship between SPOD and dynamic mode decomposition (DMD); we show that SPOD modes are in fact optimally averaged DMD modes obtained from an ensemble DMD problem for stationary flows.

Modal Analysis of Fluid Flows: An Overview
Simple aerodynamic configurations under even modest conditions can exhibit complex flows with a wide range of temporal and spatial features.
