Gas-Particle Dynamics in High-Speed Flows
Jesse Capecelatro, Justin Wagner
High-speed disperse multiphase flows are present in numerous environmental and engineering applications with complex interactions between turbulence, shock waves, and particles. Co…
Drag force of a compressible flow past a random array of spheres
Mehdi Khalloufi, Jesse Capecelatro
We perform particle-resolved simulations of subsonic and transonic flows past random arrays of spherical particles. The Reynolds number is held at to ensure the fl…
Multi-fidelity uncertainty quantification of particle deposition in turbulent pipe flow
Yuan Yao, Xun Huan, Jesse Capecelatro
Particle deposition in fully-developed turbulent pipe flow is quantified taking into account uncertainty in electric charge, van der Waals strength, and temperature effects. A fram…
Modeling high-speed gas-particle flows relevant to spacecraft landings: A review and perspectives
Jesse Capecelatro
The interactions between rocket exhaust plumes and the surface of extraterrestrial bodies during spacecraft landings involve complex multiphase flow dynamics that pose significant…
Fluid-mediated sources of granular temperature at finite Reynolds numbers
Aaron M. Lattanzi, Vahid Tavanashad, Shankar Subramaniam +1
We derive analytical solutions for hydrodynamic sources and sinks to granular temperature in moderately dense suspensions of elastic particles at finite Reynolds numbers. Modeling…
On the Utility of a Well-Mixed Model for Predicting Disease Transmission on an Urban Bus
Zhihang Zhang, Jesse Capecelatro, Kevin Maki
The transport of virus-laden aerosols from a host to a susceptible person is governed by complex turbulent airflow, and physics related to breathing, coughing and sneezing, mechani…
Multiphase turbulence modeling using sparse regression and gene expression programming
S. Beetham, J. Capecelatro
In recent years, there has been an explosion of machine learning techniques for turbulence closure modeling, though many rely on augmenting existing models. While this has proven s…
On the thermal entrance length of moderately dense gas-particle flows
S. Beetham, A. Lattanzi, J. Capecelatro
The dissipative nature of heat transfer relaxes thermal flows to an equilibrium state that is devoid of temperature gradients. The distance to reach an equilibrium temperature -- t…
A stochastic model for the hydrodynamic force in Euler--Lagrange simulations of particle-laden flows
Aaron M. Lattanzi, Vahid Tavanashad, Shankar Subramaniam +1
Standard Eulerian--Lagrangian (EL) methods generally employ drag force models that only represent the mean hydrodynamic force acting upon a particle-laden suspension. Consequently,…
Role of pulsatility on particle dispersion in expiratory flows
K. Monroe, Y. Yao, A. Lattanzi +2
Expiratory events, such as coughs, are often pulsatile in nature and result in vortical flow structures that transport respiratory particles. In this work, direct numerical simulat…
Disease transmission through expiratory aerosols on an urban bus
Zhihang Zhang, Taehoon Han, Kwang Hee Yoo +3
Airborne respiratory diseases such as SARS-CoV-2 (COVID-19) pose significant challenges for public transportation. Several recent outbreaks of SARS-CoV-2 indicate the high risk of…
Sparse identification of multiphase turbulence closures for coupled fluid--particle flows
S. Beetham, R. O. Fox, J. Capecelatro
In this work, model closures of the multiphase Reynolds-Average Navier-Stokes (RANS) equations are developed for homogeneous, fully-developed gas--particle flows. To date, the majo…
Formulating turbulence closures using sparse regression with embedded form invariance
S. Beetham, J. Capecelatro
A data-driven framework for formulation of closures of the Reynolds-Average Navier--Stokes (RANS) equations is presented. In recent years, the scientific community has turned to ma…
Inertial particle velocity and distribution in vertical turbulent channel flow: a numerical and experimental comparison
Guiquan Wang, Kee Onn Fong, Filippo Coletti +1
This study is concerned with the statistics of vertical turbulent channel flow laden with inertial particles for two different volume concentrations ( and…
