摘要

We study, in this article, the stochastic Allen–Cahn–Navier–Stokes model in a bounded domain of \(\mathbb {R}^{2}\) . The model consists of the Navier–Stokes equations for the velocity, coupled with a Allen–Cahn model for the order (phase) parameter. We prove the regularity of the solutions in a higher space. The proof uses the It \(\hat{o}\) formula and the energy method.
