The inviscid limit of the Navier-Stokes equations is one of the most fundamental and challenging problems in fluid dynamics. For domains with boundaries under no-slip boundary conditions, the problem is largely open due to large convection terms in the inviscid limit. On the whole space R2, the problem is open for irregular initial data, except for vortex patches and point vortices.
This dissertation discusses my results on the inviscid limit of the Navier-Stokes equations. My first results are to justify the inviscid limit on half-space for via a new analytic framework. The analysis is carried out for the classical no-slip boundary condi- tions as well as the critical boundary conditions. Finally, the thesis justifies the inviscid limit for vortex-wave data, which rigorously obtains the vortex-wave system derived in the early 90s by Marchioro-Pulvirenti as a vanishing viscosity limit of the Navier-Stokes equations.
