We prove the global existence of weak solutions of the Navier-Stokes equations for compressible, isothermal flow in two and three space dimensions when the initial density is close to a constant in L 2 and L ∞, and the initial velocity is small in L 2 and bounded in L 2n (in two dimensions the L 2 norms must be weighted slightly).

The Navier-Stokes equations for the motion of compressible, viscous fluids in the half-space R3 + with the no-slip boundary condition are studied. Given a constant equilibrium state (¯ρ,0), we construct a global in time, regular weak solution, provided that the initial data ρ 0,u 0 are close to the equilibrium state when measured by the.

The flow was assumed to be neutral, and no heat flux was imposed at the ground, a criterion that represents cloudy, morning, or higher-wind conditions. As a consequence, only the experimental data that also represented neutral flow conditions were used in the following by: Derivation of the Navier–Stokes equations - Wikipedia, the free encyclopedia 4/1/12 PM flow is assumed compressible an equation of state will be required, which will likely further require a conservation of energy formulation.
