We study the behaviour of the solution to the Navier-Stokes equations with vanishing viscosity and a non-slip condition in a randomly perforated domain. We consider the space where we remove holes that are i.i.d. distributed. The behaviour depends on the particle size and the viscosity of the fluid. We prove quantitative convergence results to a function , provided that the local Reynolds number is small, in the subcritical () and critical () regime. In the first case, solves the Euler equations, whereas in the second case solves the Euler-Brinkman equations. This extends the results of https://doi.org/10.1088/1361-6544/acfe56 from the periodic to the random setting. We only treat the case so that the particles do not overlap with overwhelming probability.
