I will discuss the application of time-averaging in getting rigorous error estimates of some reduced fluid models,including the incompressible approximation and quasi-geostrophic approximation.The spatial boundary can be present as a non-penetrable solid wall.I will show a very recent(and somewhat surprising)result on the ε2 accuracy of incompressible approximation of Euler equations,thanks to several decoupling properties.
