In this paper, we have investigated a bulk viscous anisotropic Universe and constrained its model parameters with recent and Pantheon compilation data. Using cosmic chronometric technique, we estimate the present value of Hubble's constant as , and by bounding our derived model with recent data, Pantheon and joint and Pantheon data respectively. The present age of the Universe is specified as Gyrs. The model favours a transitioning Universe with the transition red-shift as . We have reconstructed the jerk parameter using the observational data sets. From the analysis of the jerk parameter, it is observed that, our derived model shows a marginal departure from the concordance ΛCDM model.

比安奇 V 时空大体积粘性流体加速宇宙的建模

在本文中，我们研究了一个大块粘性各向异性宇宙，并用最近的和万神殿的编译数据约束了它的模型参数。使用宇宙计时技术，我们将哈勃常数的现值估计为，并通过将我们的派生模型分别与最近的数据、万神殿和联合以及万神殿数据进行绑定。宇宙的当前年龄被指定为Gyrs。该模型支持过渡的宇宙，过渡红移为。我们已经使用观测数据集重建了jerk 参数。从对jerk参数的分析可以看出，我们的推导模型显示出与一致性ΛCDM模型的边际偏离。
