High-order, long-time stable and parallel decoupled GBDF SAV ensemble schemes for the Navier--Stokes--Darcy flow with random hydraulic conductivity tensors
Wei-Wei Han, Fukeng Huang, Changxin Qiu
We develop and analyze high-order ensemble schemes for the unsteady Navier--Stokes--Darcy system with uncertain initial conditions, forcing terms, hydraulic conductivity tensors, a…

Numerical analysis of a 1/2-equation model of turbulence
Wei-Wei Han, Rui Fang, William Layton
The recent 1/2-equation model of turbulence is a simplification of the standard Kolmogorov-Prandtl 1-equation URANS model. Surprisingly, initial numerical tests indicated that the…
