Kaluza-Klein spacetime filled with barotropic fluid and dark energy

In this paper, we study a two-fluid cosmological model in five-dimensional Kaluza-Klein spacetime. For the two-fluid model, one fluid corresponds to model the barotropic fluid and another fluid represents the dark energy of the universe. Einstein's field equations have been solved with the interacting as well as the non-interacting two-fluid scenario. The physical consequences concerning the dark energy parameter for the interacting and non-interacting two-fluid scenario are compared in view of current observation results. The cosmological models presented in the article are best described by quintessence dark energy cosmological models of the universe. The total density parameter(omega) value remains the same; either two fluids are interacting or non-interacting. Our models are consistent with the current lambda-CDM model of the universe and show that q -> - 1 and j(t) -> 1 for large n value.
