Abstract

In the present study, we have explored the solution of homogeneous and isotropic Friedmann-Robertson-Walker (FRW) space time in the frame of  gravity proposed by Harko et al. (2011). We have considered  model of gravity and bulk viscous domain wall as an source of energy. By examining the barotropic equation of state and the rule of variation of parameter presented by Berman (1983), we have found the solution of the field equations with a proper choice of  model. We have looked into the dynamical and cosmological aspects of the model. The currently described model accelerate for  and expands at a decreasing rate. Which corresponded to recent observations of the Universe [1, 2]. According to our findings, density and bulk viscosity coefficient  is decreasing function of cosmic time . Also, we have discussed dimensionless parameters like jerk (), snap () and lerk ().
