Some Bianchi Type I Magnetized Bulk Viscous Fluid Tilted Cosmological Models

Anita Bagora, Rakeshwar Purohit


Expanding Bianchi type I magnetized bulk viscous models with two tilted fluid filled with disordered radiation and heat conduction are investigated. Here we assume a linear relation between shear and expansion, which leads to A=BC, where A, B, C are metric potentials. The coefficient of bulk viscosity is assumed to be power function of mass density. It has been shown that tilted nature of the model is preserved due to magnetic field. The various physical and geometrical properties of the models are discussed. The nature of the models in presence and absence of magnetic field and bulk viscosity are also discussed.

Key words: Cosmology; Bianchi type I universe; Tilted models; Bulk viscosity.
