Abstract

In this paper, we obtain a spatially homogeneous and anisotropic Bianchi type-V cosmological model of the universe for perfect fluid distribution with heat flow within the framework of scalar-tensor theory of gravitation proposed by Saez and Ballester (Phys. Lett. 113:467, 1986). To prevail the deterministic solutions we consider time-dependent deceleration parameter (DP) which provides the value of scale factor as a = [sinh( T)], where is arbitrary positive constant. This acclimates time-dependent deceleration parameter (DP) which affords a late time acceleration in the universe. The modified Einsteinís field equations are solved exactly and the derived model is found to be in good concordance with recent observations. The physical significance of the cosmological model has also been discussed.
