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…
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…
MFC 5.0: An exascale many-physics flow solver
Benjamin Wilfong, Henry A. Le Berre, Anand Radhakrishnan +16
Many problems of interest in engineering, medicine, and the fundamental sciences rely on high-fidelity flow simulation, making performant computational fluid dynamics solvers a mai…
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…
Simulating many-engine spacecraft: Exceeding 1 quadrillion degrees of freedom via information geometric regularization
Benjamin Wilfong, Anand Radhakrishnan, Henry Le Berre +9
We present an optimized implementation of the recently proposed information geometric regularization (IGR) for unprecedented scale simulation of compressible fluid flows applied to…
Testing and benchmarking emerging supercomputers via the MFC flow solver
Benjamin Wilfong, Anand Radhakrishnan, Henry A. Le Berre +3
Deploying new supercomputers requires testing and evaluation via application codes. Portable, user-friendly tools enable evaluation, and the Multicomponent Flow Code (MFC), a compu…
