摘要：We investigate a generic compressible two-fluid model with unequal pressures in R³. Under the help of the “effective viscous flux”, we successfully remove the technical smallness condition (see Evje-Wang-Wen [Arch Rational Mech Anal 221:1285-1316, 2016]) to establish the global existence of strong solutions for initial perturbations near equilibrium in H². Furthermore, when initial perturbations additionally belong to L¹, we obtain optimal decay rates for the solution and its spatial derivatives (from first to second order) using high-low frequency decomposition and time-weighted energy methods.
