Stationary solutions of incompressible viscous flow in a wall-driven semi-circular cavity

Acta Polytechnica, 2021
Stationary numerical solutions of incompressible viscous flow inside a wall-driven semicircular cavity are presented. After a conformal mapping of the geometry, using a body-fitted mesh, the Navier-Stokes equations are solved numerically.

An amplitude-phase (Ermakov-Lewis) approach for the Jackiw-Pi model of bilayer graphene [PDF]

, 2008
In the context of bilayer graphene we use the simple gauge model of Jackiw and Pi to construct its numerical solutions in powers of the bias potential V according to a general scheme due to Kravchenko. Next, using this numerical solutions, we develop the

Adapting the MPAS Dynamical Core for Applications Extending Into the Thermosphere

Journal of Advances in Modeling Earth Systems, 2021
To extend the nonhydrostatic global Model for Prediction Across Scales (MPAS) for deep‐atmosphere (geospace) applications, we have modified the model equations and numerics to include variable atmospheric composition and (potentially large) molecular ...
