Abstract

The present study deals with dissipative future universe without big rip in context of Eckart formalism. The generalized chaplygin gas, characterized by equation of state p=Aρ1αp=-\frac{A}{\rho^\frac{1}{\alpha}}, has been considered as a model for dark energy due to its dark-energy-like evolution at late time. It is demonstrated that, if the cosmic dark energy behaves like a fluid with equation of state p=ωρp=\omega\rho; ω<1\omega < -1, as well as chaplygin gas simultaneously then the big rip problem does not arises and the scale factor is found to be regular for all time.
