Plane symmetric viscous fluid cosmological models of the universe with a variable cosmological term are investigated. The viscosity coefficient of bulk viscous fluid is assumed to be a power function of mass density, whereas the coefficient of shear viscosity is taken as a constant. To get the deterministic solutions of the Einstein’s field equations, the free gravitational field is assumed to be of type D which is of the next order in the hierarchy of Petrov classification. The cosmological constant Λ is found to be a decreasing function of time and positive which is corroborated by the results from recent supernovae Ia observations. The physical and geometric aspects of the models are discussed.Istražujemo ravninski simetrične, viskozne i...
