Abstract

The finding article presents Bianchi type- universe in the presence of bulk viscous and DE fluid nature of a cosmological model. The solutions of field equations were obtained by assuming hybrid expansion law. The physical significance of the obtained findings illustrates the dominance of bulk viscosity in early and dominance of dark energy fluid emergences in late. This leads to indicate the presence of bulk viscosity nature more effective in early time rather than late times, and also, it shows the dominance of dark energy in late times which grants the current observational result of the universe. Certain physical and geometrical properties of the model are also discussed.
Bianchi - I型体黏度与DE宇宙学模型
这篇发现文章提出了比安奇型宇宙存在体粘性和DE流体性质的一个宇宙学模型。通过假设混合展开律,得到了场方程的解。所获得的发现的物理意义表明,早期以体粘度为主,晚期以暗能量流体为主。这就说明了体积黏性在早期比在后期更有效的存在,同时也说明了暗能量在后期的主导地位,这也证实了目前宇宙的观测结果。还讨论了模型的某些物理和几何性质。
