Discontinuous Galerkin Semidiscretization of the Information Geometric Regularized Compressible Euler Equations
Brook Eyob, Jesus Arias, Spencer H. Bryngelson +1
Shock stabilization in compressible Euler flows remains a central challenge for high-order numerical methods. Existing shock-capturing approaches, including limiters, artificial vi…
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…
Limits of constant-parameter constitutive models for hydrogels under inertial cavitation
Tianyi Chu, Joseph Beckett, Zhiren Zhu +2
Mechanical characterization of soft materials at high strain rates is challenging due to their high compliance, nonlinear viscoelastic behavior, and potentially history-dependent r…
Shocks without shock capturing: Information geometric regularization of finite volume methods for Navier--Stokes-like problems
Anand Radhakrishnan, Benjamin Wilfong, Spencer H. Bryngelson +2
Shock waves in high-speed fluid dynamics produce near-discontinuities in the fluid momentum, density, and energy. Most contemporary works use artificial viscosity or limiters as nu…
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…
