A load balanced chemistry model with analytical Jacobian for faster reactive simulations in OpenFOAM
Bulut Tekgül, Heikki Kahila, Petteri Peltonen +3
In this study, we introduce a novel open-source chemistry model for OpenFOAM to speed-up the reactive computational fluid dynamics (CFD) simulations using finite-rate chemistry. Fi…
Polymer drag reduction in surfactant-contaminated turbulent bubbly channel flows
Daulet Izbassarov, Zaheer Ahmed, Pedro Costa +3
Polymer additives are commonly utilized to manipulate bubbly flows in various applications. Here, we investigate the effects of clean and contaminated bubbles driven upwards (upflo…
Fast reactive flow simulations using analytical Jacobian and dynamic load balancing in OpenFOAM
Ilya Morev, Bulut Tekgül, Mahmoud Gadalla +5
Detailed chemistry-based computational fluid dynamics (CFD) simulations are computationally expensive due to the solution of the underlying chemical kinetics system of ordinary dif…
DLBFoam: An open-source dynamic load balancing model for fast reacting flow simulations in OpenFOAM
Bulut Tekgül, Petteri Peltonen, Heikki Kahila +2
Computational load imbalance is a well-known performance issue in multiprocessor reacting flow simulations utilizing directly integrated chemical kinetics. We introduce an open-sou…
A numerical study on combustion mode characterization for locally stratified dual-fuel mixtures
Shervin Karimkashi, Heikki Kahila, Ossi Kaario +2
Combustion modes in locally stratified dual-fuel (DF) mixtures are numerically investigated for methanol n-dodecane blends under engine-relevant pressures. In the studied constant-…
Modelling aerosol transport and virus exposure with numerical simulations in relation to SARS-CoV-2 transmission by inhalation indoors
Ville Vuorinen, Mia Aarnio, Mikko Alava +27
We provide research findings on the physics of aerosol dispersion relevant to the hypothesized aerosol transmission of SARS-CoV-2. We utilize physics-based modeling at different le…
Host--parasite models on graphs
Matti Peltomaki, Ville Vuorinen, Mikko Alava +1
The behavior of two interacting populations, ``hosts''and ``parasites'', is investigated on Cayley trees and scale-free networks. In the former case analytical and numerical argume…
