Aircraft aerodynamic design often involves evaluating flow conditions that span low
subsonic to transonic or even supersonic Mach numbers. Compressible flow solvers are a …

For low-speed turbulent flows governed by compressible Navier–Stokes equations, the
large disparity of phase velocities between hydrodynamic wave and acoustic wave leads to …

A preconditioning framework for the numerical simulation of non-thermal streamer
discharges is developed using the Jacobian-free Newton-Krylov (JFNK) method. A reduced …

The aerodynamic design of aircraft often involves evaluating flow conditions that span low
subsonic to transonic, or even supersonic Mach numbers. Compressible flow solvers are a …

Fluids at supercritical thermodynamic conditions are inherently complex due to the large
variations in thermodynamic and transport properties. Multiple recent numerical and …

We introduce a novel Newton–Krylov (NK)-based fully implicit algorithm for solving fluid
flows in a wide range of flow conditions—from variable density nearly incompressible to …

The paper focuses on developing and studying efficient block preconditioners based on
classical algebraic multigrid for the large-scale sparse linear systems arising from the fully …

Designing supersonic transport (SST) aircraft requires accounting for performance and
stability at high-speed and low-speed conditions. Previous work demonstrated that there is a …

THE goal of this research is to investigate and characterize the dynamics of a molten metal
pool through modeling and simulaiton. Two manufacturing processes are of interest, laser …
