Add to ORKGWe discuss a class of nonsingular spherically-symmetric cosmological models with radial heat flux and variable cosmological term Λ(t). Three different exact solutions of the Einstein’s field equations are obtained for both perfect fluid and fluid with bulk viscosity. It turns out that the cosmological term Λ(t) is a decreasing function of time, what is consistent with recent observations of type Ia supernovae. PACS numbers: 98.80.-k, 98.80.Es UDC 524.8
