Abstract

A class of exact imperfect fluid solutions of the Brans-Dicke (BD) field equations, in which the geometrical part is identical to that of BD-FRW dust model withk=0 is presented. The solutions are functions of time and radial coordinates and satisfy all necessary energy and thermodynamic conditions.
