摘要

Bianchi type- \({VI}_{0}\) space–time solution within the context of bulk viscosity is presented in this paper. We impose a condition \(\xi \theta =\alpha \) (constant) where \(\xi \) represents the coefficient of bulk viscosity. By using the shear (σ), which is proportional to the expansion scalar (θ), in the model, Einstein's field equations have been precisely solved. This gives rise to \(A={B}^{n}\) where n (n > 1) is a positive constant and both A and B can be described as metric functions. We examine the model's geometrical and physical properties when bulk viscosity is present.
