Motivated by two seminal models proposed to explain the Universe acceleration, this paper is devoted to study a hybrid model which is constructed through a generalized Chaplygin gas with the addition of a bulk viscosity. We call the model a viscous generalized Chaplygin gas (VGCG) and its free parameters are constrained through several cosmological data like the Observational Hubble Parameter, Type Ia Supernovae, Baryon Acoustic Oscillations, Strong Lensing Systems, HII Galaxies and using Joint Bayesian analysis. In addition, we implement a Om-diagnostic to analyze the VGCC dynamics and its difference with the standard cosmological model. The hybrid model shows important differences when compared with the standard cosmological model. Finally, based on our Joint analysis we find that the VGCG could be an interesting candidate to alleviate the well-known Hubble constant tension.

受提议用来解释宇宙加速度的两个主要模型的启发，本文致力于研究一种混合模型，该模型是通过广义的Chaplygin气体加上体积粘度而构建的。我们称该模型为粘性广义Chaplygin气体（VGCG），其自由参数受到几种宇宙学数据的约束，例如观测哈勃参数，Ia型超新星，重子声振荡，强透镜系统，HII星系以及使用联合贝叶斯分析。此外，我们实施了Om诊断，以分析VGCC动力学及其与标准宇宙学模型的差异。与标准宇宙学模型相比，混合模型显示出重要的差异。最后，
