Coupled Rayleigh--Taylor and Faraday instabilities in vertically vibrated cylindrical containers
Tianyi Chu, Benjamin Wilfong, Timothy Koehler +2
Interfacial instabilities govern the mixing in confined multiphase flows. Yet, the two mechanisms that drive them are usually studied independently: the pressure-gradient-driven Ra…
Energy dissipation mechanisms in an acoustically-driven slit
Haocheng Yu, Tianyi Chu, Spencer H. Bryngelson
We quantify how incident acoustic energy is converted into vortical motion and viscous dissipation for a two-dimensional plane-wave passing through a slit geometry. We perform dire…
Hardware-Accelerated Phase-Averaging for Cavitating Bubbly Flows
Diego Vaca-Revelo, Benjamin Wilfong, Spencer H. Bryngelson +1
We present a comprehensive validation, performance characterization, and scalability analysis of a hardware-accelerated phase-averaged multiscale solver designed to simulate acoust…
Competing Mechanisms at Vibrated Interfaces of Density-Contrast Fluids
Tianyi Chu, Benjamin Wilfong, Timothy Koehler +2
Fluid--fluid interfacial instability and subsequent fluid mixing are ubiquitous in nature and engineering. The hydrodynamic instability of fluid interfaces has long centered on the…
Incompressible Navier-Stokes solve on noisy quantum hardware via a hybrid quantum-classical scheme
Zhixin Song, Robert Deaton, Bryan Gard +1
Partial differential equation solvers are required to solve the Navier-Stokes equations for fluid flow. Recently, algorithms have been proposed to simulate fluid dynamics on quantu…
Targeted computation of nonlocal closure operators via an adjoint-based macroscopic forcing method
Jessie Liu, Florian Schäfer, Spencer H. Bryngelson +2
Reynolds-averaged Navier--Stokes (RANS) closure must be sensitive to the flow physics, including nonlocality and anisotropy of the effective eddy viscosity. Recent approaches used…
RoseNNa: A performant, portable library for neural network inference with application to computational fluid dynamics
Ajay Bati, Spencer H. Bryngelson
The rise of neural network-based machine learning ushered in high-level libraries, including TensorFlow and PyTorch, to support their functionality. Computational fluid dynamics (C…
A spectral boundary integral method for simulating electrohydrodynamic flows in viscous drops
Mohammadhossein Firouznia, Spencer H. Bryngelson, David Saintillan
A weakly conducting liquid droplet immersed in another leaky dielectric liquid can exhibit rich dynamical behaviors under the effect of an applied electric field. Depending on mate…
A seven-equation diffused interface method for resolved multiphase flows
Achyut Panchal, Spencer H. Bryngelson, Suresh Menon
The seven-equation model is a compressible multiphase formulation that allows for phasic velocity and pressure disequilibrium. These equations are solved using a diffused interface…
Conditional moment methods for polydisperse cavitating flows
Spencer H. Bryngelson, Rodney O. Fox, Tim Colonius
The dynamics of cavitation bubbles are important in many flows, but their small sizes and high number densities often preclude direct numerical simulation. We present a computation…
