We prove existence of weak solutions to the compressible Navier-Stokes system in barotropic regime (adiabatic coefficient γ> 3∕2, in three dimensions, γ> 1 in two dimensions) with large velocity prescribed at the boundary and large density prescribed at the inflow boundary of a bounded ...
I am new to COMSOL and I've been trying to model some incompressible Navier-Stokes system with variable viscosity, a Carreau viscosity to be specific. I have used the CFD module to model this with the single phase laminar flow which also has Carreau fluid properties, and now I'd like ...

3.By applying Gronwall′s inequality,this paper proves the uniqueness of the weak solution ofcompressible Navier-Stokes equationswith vacuum and gravitational force in Lagrangian coordinates.通过运用Gronwall不等式,在Lagrangian坐标系下,证明了带真空和外力的可压缩Navier-Stokes方程初边值问题弱解的唯一性。
In this paper, we prove that there exists a unique global strong solution to the three-dimensional full compressible Navier-Stokes equations with vacuum at infinity, provided that the initial mass is small in some sense. The initial vacuum may also appear in a subset of $R^3$ besides at ...

iteration step is used to prescribe new variable coefficients for the next iteration step. The contracting property of the Navier-Stokes-wave system is maintained by taking a sufficiently short timeto ensure closeness of the Jacobian and the inverse matrix of the flow map to their initial states....
