Abstract

We have investigated FRW cosmological models with constant Ratio of bulk viscosity and matter density in general relativity. Functional relation on Hubble parameter is assumed, which yield constant value of deceleration parameter. The solution of field equations has been solved the best value for the Hubble parameter, energy density, isotropic pressure and cosmological term at present and at recombination. The physical and kinematical behavior of the model is also studied.
