Abstract—Bianchi type I bulk viscous fluid tilted cosmological model filled with dust fluid is investigated. We assume that Kzq=(constant), where z is the coefficient of bulk viscosity and q is the expansion in the model. It has been assumed that the universe is filled with dust together with A = BC, where A, B and C are metric potentials. Special model is also investigated in the absence of bulk viscosity. The physical and geometrical aspects of the model in the presence and absence of bulk viscosity are also discussed.
