Abstract
In this paper we consider several phenomenological models ofvariable Λ. Model of a flat Universe with variable Λand G is accepted. It is well known, that varying G andΛ gives rise to modified field equations and modifiedconservation laws, which gives rise to many different manipulationsand assumptions in literature. We will consider two component fluid,which parameters will enter to Λ. Interaction between fluidswith energy densities ρ1 and ρ2 assumed asQ = 3Hb(ρ1+ρ2). We have numerical analyze of importantcosmological parameters like EoS parameter of the composed fluid anddeceleration parameter q of the model.
