Description
A flat Friedmann-Robertson-Walker (FRW) cosmological model with perfect fluid has been investigated within the framework of the particle creation mechanism. Perfect fluid isentropic particle creation rate as a function of Hubble parameter has been incorporated. By considering a simple parametrization of Hubble parameter, we discuss the cosmological scenarios through time evolution of the cosmological parameters. We examine the different regimes of the universe by studying the phase transition from decelerated to accelerated era. We also explore the classical stability of model and the state-finder diagnostic for highlighting the departure of the considered cosmological model from the Cold Dark Matter (CDM) model.
