Slow-growth approximation for near-wall patch representation of wall-bounded turbulence
Sean P. Carney, Robert D. Moser
Wall-bounded turbulent shear flows are known to exhibit universal small-scale dynamics that are modulated by large-scale flow structures. Strong pressure gradients complicate this…
A pseudospectral method for direct numerical simulation of low-Mach, variable-density, turbulent flows
Bryan W. Reuter, Todd A. Oliver, Robert D. Moser
A novel algorithm for the direct numerical simulation of the variable-density, low-Mach Navier-Stokes equations extending the method of Kim, Moin, and Moser (1987) for incompressib…
Extensions to Multifidelity Monte Carlo Methods for Simulations of Chaotic Systems
Todd A. Oliver, Christopher S. Simmons, Robert D. Moser
Multifidelity Monte Carlo methods often rely on a preprocessing phase consisting of standard Monte Carlo sampling to estimate correlation coefficients between models of different f…
Numerical dispersion effects on the energy cascade in large-eddy simulation
Gopal R. Yalla, Todd A. Oliver, Robert D. Moser
Implicitly filtered large-eddy simulation (LES) is by nature numerically under-resolved. With the sole exception of Fourier-spectral methods, discrete numerical derivative operator…
Bayesian inference of an uncertain generalized diffusion operator
Teresa Portone, Robert D. Moser
This paper defines a novel Bayesian inverse problem to infer an infinite-dimensional uncertain operator appearing in a differential equation, whose action on an observable state va…
Active model split hybrid RANS/LES
Sigfried W. Haering, Todd A. Oliver, Robert D. Moser
Reliably predictive simulation of complex flows requires a level of model sophistication and robustness exceeding the capabilities of current Reynolds-averaged Navier-Stokes (RANS)…
