摘要
In this paper, we study the emergent universe (EU) with interacting fluids in the background of Bianchi type I (BI) universe model. For this purpose, we consider polytropic equation of state (EoS) which constitutes three non-interacting fluids. In order to check the viability of the cosmological models, we take a two-fluid model interacting with dust fluid and a three-fluid model in which each fluid has nonlinear EoS interacting at t >= t(0). It turns out that both models are realistic cosmological viable. We also check the validity of the generalized second law of thermodynamics (GSLT) for EU with interacting fluids. Finally, we study its validity in the framework of nonlinear electrodynamics (NLED) on apparent horizon.
