This analysis demonstrates the role of shear viscosity on pressure and energy density in Bianchi Type-VI models, implying insights into early universe behavior.
This paper explores the anisotropic nature of the Cosmological Model Bianchi Type -VI with Viscous Fluid in the presence of cosmological constant ࢫ. Cosmological Model Bianchi Type -VI helps in understanding anisotropic behaviour in the early universe and its implications. To find an exact solution for this model, a supplementary condition between the metric potential is used. Also, it is used the coefficient of shear viscosity is proportional to the scale of expansion, i.e., ࣁ ∝ ࣂ. In this study, I assumed that the viscosity coefficient of a bulk viscosity fluid is a simple power function of energy density, ࣈ)࢚ = (ࣈ࣋ ࢘ and it is solved for ࢘ = and ࢘ = . The behaviour of cosmological parameters like pressure, energy density will be analysed, and it is also found that the cosm
