摘要：

We obtain the exact solution of a recently proposed two-phase flow model of the Rayleigh-Taylor mixing zone, in the incompressible, large time scaling limit. The scaling limit equations are the renormalization group equations for this problem. Our results show that the large time behavior of the incompressible Rayleigh-Taylor mixing layer is determined by a renormalization group fixed point. Our solution allows independent pressures in each fluid. The pressures do not equilibrate dynamically, implying that distinct pressures for each phase is an intrinsic aspect of this problem.
