摘要: The present work deals with a spherically symmetric space–time which is asymptotically (at spatial infinity) FRW and represents wormhole configuration: matter component divided into two parts—(a) dissipative but homogeneous isotropic fluid, (b) an inhomogeneous anisotropic barotropic fluid. Evolving solutions are obtained when fluid phantom in nature there big rip singularity at the end. Here phenomena due to particle creation mechanism non-equilibrium thermodynamics. Using process be adiabatic, pressure expressed linearly rate. For choices of rate as function Hubble parameter, equation state parameter constrained domain, except one choice, it possible have configuration normal
