Abstract
The new dynamical solutions of Einstein's equations with perfect fluid in space-times with FLRW asymptotic behaviour, derived recently \cite{Cot,Cot1,Cot2}, may describe evaporating black holes whose masses dissipate into dust. The time evolution of the black hole and dust masses of simple models of evaporating black holes are studied using analytical and graphical methods.
