We study stochastic Navier-Stokes equations in two dimensions with respect to periodic boundary conditions. The equations are perturbed by a nonlinear multiplicative stochastic forcing with linear growth (in the velocity) driven by a cylindrical Wiener process. We establish convergence rates for a finite-element based space-time approximation with respect to convergence in probability (where the error is measure in the $L^\infty_tL^2_x\cap L^2_tW^{1,2}_x$-norm). Our main result provides linear… 
Numerical and convergence analysis of the stochastic Lagrangian averaged Navier-Stokes equations
A finite element based space-time discretization for solving the stochastic Lagrangian averaged NavierStokes equations of incompressible fluid turbulence with multiplicative random forcing under nonperiodic boundary conditions within a bounded polygonal domain.
Error analysis for 2D stochastic Navier-Stokes equations in bounded domains
It is proved optimal convergence rates in the energy norm with respect to convergence in probability, that is convergence of order (almost) 1/2 in time and 1 in space.
Analysis of Chorin-Type Projection Methods for the Stochastic Stokes Equations with General Multiplicative Noises
It is proved that all spatial error constants contain a growth factor, which explains the deteriorating performance of the standard Chorin scheme when $k\to 0$ and the space mesh size is fixed as observed earlier in the numerical tests of [9].
Analysis of Fully Discrete Mixed Finite Element Methods for Time-dependent Stochastic Stokes Equations with Multiplicative Noise
Strong convergence with rates is established not only for the velocity approximation but also for the pressure approximation (in a time-averaged fashion) for the time-dependent stochastic Stokes equations with multiplicative noise.
High moment and pathwise error estimates for fully discrete mixed finite element approximations of the Stochastic Stokes Equations with Multiplicative Noises
The main idea for deriving the high moment error estimates for the velocity approximation is to use a bootstrap technique starting from the second moment error estimate, which results in a pathwise error estimate which is sub-optimal in the energy norm.
Numerical analysis of 2D Navier-Stokes equations with additive stochastic forcing
This work proposes and studies a temporal, and spatio-temporal discretisation of the 2D stochastic Navier–Stokes equations in bounded domains supplemented with no-slip boundary conditions and shows strong rate (up to) 1 in probability for a correspondingDiscretisation in space and time.

Optimally Convergent Mixed Finite Element Methods for the Stochastic Stokes Equations
It is shown that eliminating this gradient part from the noise in the numerical scheme leads to optimally convergent mixed finite element methods, and that this conceptual idea may be used to retool numerical methods that are well-known in the deterministic setting, including pressure stabilization methods, so that their optimal convergence properties can still be maintained in the stochastic setting.

Rates of Convergence for Discretizations of the Stochastic Incompressible Navier-Stokes Equations
It turns out that it is the interaction of Lagrange multipliers with the stochastic forcing in the scheme which limits the accuracy of general discretely LBB-stable space discretizations, and strategies to overcome this problem are proposed.
Strong $L^2$ convergence of time numerical schemes for the stochastic two-dimensional Navier–Stokes equations

Finite element approximation of the nonstationary Navier-Stokes problem. I : Regularity of solutions and second-order error estimates for spatial discretization
Second-order error estimates are proven for spatial discretization, using conforming or nonconforming elements, and indicate a fluid-like behavior of the approximations, even in the case of large data, so long as the solution remains regular.

Optimal strong convergence is shown for Chorin's time-splitting scheme in the case of solenoidal noise, while computational counterexamples show poor convergence behavior in the cases of general stochastic forcing.

Although the author is not able in this case to compute a pathwise order of the approximation, the weaker notion of order in probability is introduced and the results of the globally Lipschitz case are generalized.
