Performance of explicit and IMEX MRI multirate methods on complex reactive flow problems within modern parallel adaptive structured grid frameworks
John J. Loffeld, Andy Nonaka, Daniel R. Reynolds +2
Large-scale multiphysics simulations are computationally challenging due to the coupling of multiple processes with widely disparate time scales. The advent of exascale computing s…
A high-order spectral deferred correction strategy for low Mach number flow with complex chemistry
Will Pazner, Andrew Nonaka, John Bell +2
We present a fourth-order finite-volume algorithm in space and time for low Mach number reacting flow with detailed kinetics and transport. Our temporal integration scheme is based…
Low Mach Number Fluctuating Hydrodynamics of Binary Liquid Mixtures
A. J. Nonaka, Y. Sun, J. B. Bell +1
Continuing on our previous work [ArXiv:1212.2644], we develop semi-implicit numerical methods for solving low Mach number fluctuating hydrodynamic equations appropriate for modelin…
Efficient Variable-Coefficient Finite-Volume Stokes Solvers
M. Cai, A. J. Nonaka, J. B. Bell +2
We investigate several robust preconditioners for solving the saddle-point linear systems that arise from spatial discretization of unsteady and steady variable-coefficient Stokes…
Low Mach Number Fluctuating Hydrodynamics of Diffusively Mixing Fluids
A. Donev, A. J. Nonaka, Y. Sun +3
We formulate low Mach number fluctuating hydrodynamic equations appropriate for modeling diffusive mixing in isothermal mixtures of fluids with different density and transport coef…
