The general class of Bianchi cosmological models with viscous fluid and particle creation in Brans-Dicke theory

This paper deals with the general class of Bianchi cosmological models with bulk viscosity and particle creation described by full causal thermodynamics in Brans-Dicke theory.We discuss three types of average scale-factor solutions for the general class of Bianchi cosmological models by using a special law for the deceleration parameter which is linear in time with a negative slope.The exact solutions to the corresponding field equations are obtained in quadrature form and solutions to the Einstein field equations are obtained for three different physically viable cosmologies.All the physical parameters are calculated and discussed in each model.
