D. D. Pawar, V. J. Dagwal, S. P. Shahare, Y. S. Solanke


 In this paper, we have investigated two-fluid Kantowski-Sachs cosmological models with matter and radiating source in the scalar-tensor theory of gravitation proposed by Saez and Ballester. Two-fluid model in Saez and Ballester theory of gravitation, one fluid represents the matter content of the universe and another fluid is the CMB radiation. To get the deterministic model, we have assumed that a relation between metric potentials A = Bn, where A and B are metric potentials and n is constant. We have also investigated the behaviors of some physical parameters.
