Abstract. We study the spatially homogeneous and isotropic Friedman-Robertson-Walker (FRW) cosmological model with barotropic viscous fluid in the framework of f(T) theory of gravity, where T denotes the torsion scalar. The behavior of accelerating universe is discussed for some well-known f(T) models with the help of a power law solution. Also we have discussed the basic thermodynamic aspects of the model. For a different option of barotropic fluid, we have generated a class of coefficient of bulk viscous, thermodynamic temperatures and Entropy densities of the models. The physical and geometric properties of cosmological models are also discussed.
