Two-equation eddy-viscosity turbulence models for engineering applications
TL;DR: In this paper, two new two-equation eddy-viscosity turbulence models are presented, which combine different elements of existing models that are considered superior to their alternatives.
Numerical solution of the Euler equations by finite volume methods using Runge Kutta time stepping schemes
TL;DR: In this paper, a new combination of a finite volume discretization in conjunction with carefully designed dissipative terms of third order, and a Runge Kutta time stepping scheme, is shown to yield an effective method for solving the Euler equations in arbitrary geometric domains.

The application of preconditioning in viscous flows
Y.-H. Choi,C. L. Merkle +1 more
TL;DR: A time-derivative preconditioning algorithm that is effective over a wide range of flow conditions from inviscid to very diffusive flows and from low speed to supersonic flows has been developed and convergence rates are shown to be accelerated by as much as two orders of magnitudes.
