Abstract |
This paper is devoted to study the generalized Chaplygin gas models in Bianchi type III space – time geometry with time varying bulk viscosity, cosmological and gravitational constants. We are considering the condition on metric potential n n t m R R t m R R R R 2 3 3 1 2 2 1 1 , . Also to obtain deterministic models we have considered physically reasonable relations like p P , r 0 and the equation of state for generalized Chaplygin gas given by B . A new set of solutions of Einstein’s field equations have been obtained in Eckart theory, truncated theory and full causal theory. Physical behaviour of the models have been discussed. Keywords: Bianchi type III, Bulk viscosity, Cosmological constant, Gravitational constant, Generalized Chaplygin gas. | |||||||||
