Warm inflation model with bulk viscous pressure in the context of “intermediate inflation” where the cosmological scale factor expands as a(t) = a0 exp(At^ f ), is studied. The characteristics of this model in slow-roll approximation and in high dissipative regime are presented in two cases: 1—Dissipative parameter Gamma as a function of scalar field φ and bulk viscous coefficient ζ as a function of energy density ρ. 2—Gamma and ζ are constant parameters. Scalar, tensor perturbations and spectral indices for this scenario are obtained. The cosmological parameters appearing in the present model are constrained by recent observational data (WMAP7).
