摘要：
In this paper we study varying generalized Chaplygin gas which has viscosity in presence of cosmological constant and space curvature. By using well-known forms of scale factor in non-linear differential equation we obtain behavior of dark energy density numerically. We use observational data to fix solution and discuss about stability of our system.
