Model calculations describing the flow of material heated by irradiation into the shadow zone around L₁ are described. In dwarf novae with very short periods (P≈1-2 hrs) the resulting enhancement in the mass outflow rate is very large: M/M₀≈10-30. In systems with periods just above the period gap (P≈4 hrs) the enhancement is smaller: M/M₀≈2-6. In systems with longer periods (P≈6 hrs), however, it turns out that the flow does not reach the vicinity of L₁ and, consequently, the enhancement is negligibly small. This means that irradiation induced enhanced mass outflow plays important role in SU UMa stars but is negligible in Z Cam stars.
