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…
Fast integration method for averaging polydisperse bubble population dynamics
Spencer H. Bryngelson
Ensemble-averaged polydisperse bubbly flow models require statistical moments of the evolving bubble size distribution. Under step forcing, these moments reach statistical equilibr…
Transmission of High-Amplitude Sound through Leakages of Ill-fitting Earplugs
Haocheng Yu, Krishan K. Ahuja, Lakshmi N. Sankar +1
High sound pressure levels (SPL) pose notable risks in loud environments, particularly due to noise-induced hearing loss. Ill-fitting earplugs often lead to sound leakage, a phenom…
Quantum lattice Boltzmann algorithm for heat transfer with phase change
Christopher L. Jawetz, Zhixin Song, Spencer H. Bryngelson +1
Heat transfer involving phase change is computationally intensive due to moving phase boundaries, nonlinear computations, and time step restrictions. This paper presents a quantum…
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…
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…
