Strong $$L^2$$ convergence of time Euler schemes for stochastic 3D Brinkman–Forchheimer–Navier–Stokes equations

We prove that some time Euler schemes for the 3D Navier-Stokes equations modified by adding a Brinkman-Forchheimer term and random perturbation converge in $L^2(\Omega)$. This extends previous results concerning strong rate of convergence discretization 2D Navier Stokes equations. Unlike case, our proposed model with allows order almost 1/2, is independent viscosity parameter.
