Multilevel radial basis function surrogates for noise-robust DSMC-CFD coupling
Arshad Kamal, Arun K. Chinnappan, James R. Kermode +1
Hybrid methods for simulating rarefied gas flows reduce computational cost by coupling a particle-based model, typically the direct simulation Monte Carlo (DSMC) method, to a conti…
A correction tensor for approximating drag on slow-moving particles of arbitrary shape
Duncan A. Lockerby
A new form of the Cunningham correction factor is presented that requires no experimental fitting. It is expanded to provide a predictive heuristic for non-spherical particles, via…
uniGasFoam: a particle-based OpenFOAM solver for multiscale rarefied gas flows
Nikos Vasileiadis, Giorgos Tatsios, Craig White +3
This paper presents uniGasFoam, an open-source particle-based solver for multiscale rarefied gas flow simulations, which has been developed within the well-established OpenFOAM fra…
A DSMC-CFD coupling method using surrogate modelling for low-speed rarefied gas flows
Giorgos Tatsios, Arun K. Chinnappan, Arshad Kamal +7
A new Micro-Macro-Surrogate (MMS) hybrid method is presented that couples the Direct Simulation Monte Carlo (DSMC) method with Computational Fluid Dynamics (CFD) to simulate low-sp…
First-order analysis of slip flow at the microscale and nanoscale
Duncan A. Lockerby
A convenient approach to derive simple expressions for properties of Stokes flows with low levels of slip is presented. The method is based on a series expansion of a Stokes-flow s…
Thermal capillary waves on bounded nanoscale thin films
Jingbang Liu, Chengxi Zhao, Duncan A. Lockerby +1
The effect of confining walls on the fluctuation of a nanoscale thin film's free surface is studied using stochastic thin-film equations (STFEs). Two canonical boundary conditions…
