Existence and upper semicontinuity of random attractors for the 2D stochastic convective Brinkman-Forchheimer equations in bounded domains

In this work, we discuss the large time behaviour of the solutions of two-dimensional stochastic convective Brinkman-Forchheimer (SCBF) equations on bounded domains. Under the functional set-ting V ? H ? V', whereH and V are appropriate separable Hilbert spaces and the fact that the embedding V ? H is compact, we establish the existence of random attractors in H for the stochas-tic flow generated by 2D SCBF equations perturbed by additive noise. We prove the upper semicontinuity of the random attrac-tors for 2D SCBF equations in H, when the coefficient of random term approaches zero. Moreover, we obtain the existence of random attractors in a more regular space V, using the pullback flattening property. The existence of random attractors ensures the existence of invariant compact random set and hence we show the existence of an invariant measure for 2D SCBF equations. Finally, we also com-ment on the uniqueness of invariant measures.
