  Following Abbatiello et al. [ DCCDS-A (41), 2020], we introduce dissipative
turbulent solutions to a simple model of a mixture of two non interacting
compressible fluids {\tc filling a bounded domain with general non zero
inflow/outflow boundary conditions.} We prove existence of such solutions for
all adiabatic coefficients $\gamma>1$, their compatibility with classical
solutions, the relative energy inequality, and the weak strong uniqueness
principle in this class. The class of dissipative turbulent solutions is so far
the largest class of generalized solutions which still enjoys the weak strong
uniqueness property.
