The present work deals with a cosmological model having particle creationmechanism in the framework of irreversible thermodynamics. In the second ordernon-equilibrium thermodynamical prescription, the particle creation rate istreated as the dissipative effect. The non-equilibrium thermodynamical processis assumed to be isentropic, and, as a consequence, the entropy per particle isconstant, and, hence, the dissipative pressure can be expressed linearly interms of the particle creation rate in the background of the homogeneous andisotropic flat FLRW model. By proper choice of the particle creation rate as afunction of the Hubble parameter, the model shows the evolution of the universestarting from the inflationary scenario to the present accelerating phase,considering the cosmic matter as normal perfect fluid with barotropic equationof state.
