Kaluza-Klein Mesonic Cosmological Model with Two-Fluid Source

Abstract

In this paper we have investigated five dimensional Kaluza-Klein space-time describing two-fluid source in the context of zero-mass scalar field. Here one fluid is radiation field modeling the cosmic microwave background while the other is a matter field, modeling material content of the universe. We have obtained a deterministic solution assuming a functional relation between two metric coefficients and baratropic equation of state for ρ_m and p_m. The radiation and matter content of the universe are in interactive phase. The behaviors of fluid parameters and kinematical parameters of the models are also discussed.
