论文摘要
我们为可压缩的Navier-Stokes方程提供了一种完全离散的近似技术，该方程在时间和空间，半幅图上是二阶精确的，并保证保证是不变的域。对时间步的限制是标准双曲线CFL条件，即$τ\ lyssim \ mathcal {o}（h）/v $，其中$ v $是某些参考速度量表，而$ h $ the典型的网格size。
We present a fully discrete approximation technique for the compressible Navier-Stokes equations that is second-order accurate in time and space, semi-implicit, and guaranteed to be invariant domain preserving. The restriction on the time step is the standard hyperbolic CFL condition, ie $τ\lesssim \mathcal{O}(h)/V$ where $V$ is some reference velocity scale and $h$ the typical meshsize.
