摘要: Inspired by thermodynamical dissipative phenomena, we consider bulk viscosity for dark fluid in a spatially flat two-component Universe. Our viscous energy model represents phantom-crossing which avoids big-rip singularity. We propose non-minimal derivative coupling scalar field with zero potential leading to accelerated expansion of the Universe framework model. In this approach, constant, $$\kappa $$ , is related coefficient, $$\gamma and present density, $$\varOmega _\mathrm{DE}^0$$ . This bounded as \in [-1/9H_0^2(1-\varOmega _\mathrm{DE}^0), 0]$$ implement recent observational data sets including joint light-curve analysis (JLA) SNIa, gamma ray bursts (GRBs) most luminous astrophysical objects at high redshifts, baryon acoustic oscillations (BAO) from different surveys, Hubble parameter HST project, Planck CMB power spectrum lensing constrain free parameters.
