Hubble Parameters

Bianchi type I tilted bulk viscous fluid cosmological model filled with dust fluid is investigated. We assume that (constant), where is the coefficient of bulk viscosity and is the expansion in the model. It has been assumed that the expansion in the model is only in two directions; that is, one of the components of Hubble parameters is zero. The physical and geometrical aspects of the model in the presence and absence of bulk viscosity are also discussed. Also, we have discussed two special models and their physical properties. From this, we present a particular example based on dust fluid.

Bulk Viscous

Bianchi type I bulk viscous fluid tilted cosmological model filled with disordered radiation and heat conduction is investigated. We assume that (constant), where is the coefficient of bulk viscosity and  is the expansion in the model. Here, we assume a linear relation between shear and expansion i.e. =constant, which leads to A=BC, where A, B, C are metric potentials. The physical and geometrical aspects of the model in the presence and absence of bulk viscosity are also discussed.
