“…[7,40,41] for some early works; recently there are some rigorous justifications of such noise in fluid equations, see [27,28] for results in 2D case and also [15] where the examples include 3D Navier-Stokes equations and primitive equations. There are several papers [8,23,9,35] on the vorticity form of stochastic 2D Euler equations with transport noise, establishing well-posedness for initial data of various regularity. In recent years, there have been intensive investigations on scaling limits of SPDEs with transport noise to deterministic limit equations with an additional viscous term, see e.g.…”
