Coefficient of bulk viscosity $\\zeta$ is assumed as a simple linear function of Hubble parameter $H$ (i.e. $\\zeta=\\zeta_0+\\zeta_1 H$, where $\\zeta_0$ and $\\zeta_1$ are constants). The Einstein field equations are solved explicitly by using a law of variation for the Hubble parameter, which yields a constant value of deceleration parameter. Physical and kinematical parameters of the models are discussed.
