A parametric acceleration of multilevel Monte Carlo convergence for nonlinear variably saturated flow
Prashant Kumar, Carmen Rodrigo, Francisco J. Gaspar +1
We present a multilevel Monte Carlo (MLMC) method for the uncertainty quantification of variably saturated porous media flow that are modeled using the Richards' equation. We propo…
Stochastic turbulence modeling in RANS simulations via Multilevel Monte Carlo
Prashant Kumar, Martin Schmelzer, Richard P. Dwight
A multilevel Monte Carlo (MLMC) method for quantifying model-form uncertainties associated with the Reynolds-Averaged Navier-Stokes (RANS) simulations is presented. Two, high-dimen…
On local Fourier analysis of multigrid methods for PDEs with jumping and random coefficients
Prashant Kumar, Carmen Rodrigo, Francisco J. Gaspar +1
In this paper, we propose a novel non-standard Local Fourier Analysis (LFA) variant for accurately predicting the multigrid convergence of problems with random and jumping coeffici…
Investigation of Kelvin-like solid foams for potential engineering applications: An attractive set of geometrical and thermo-hydraulic properties
Prashant Kumar
Open cell foams have diverse industrial applications e.g. heat exchangers, structured reactors, filtration due to their unique properties such as high porosity and high specific su…
