Description
We describe numerical simulations of stochastic fluid dynamics near a critical point in the phase diagram. Using a Metropolis scheme, we evolve a conserved charge coupled to the momentum density of the fluid. This theory, known as model H, is expected to describe the nonequilibrium dynamics in the vicinity of a QCD critical point. We verify dynamic scaling near the critical point of a two and three-dimensional fluid and observe a crossover from the mean field value of the associated critical exponent to the expected model H value. This crossover is governed by the values of the correlation length and the renormalized sheer viscosity.
