In this paper a Verigin problem with kinetic condition is considered. The existence and uniqueness of a classical solution locally in time of this problem are obtained.
In this paper we consider Verigin problem with surfaCe tension at freeboundary:where Ω1(t),Ω2(t) are regions of water and oil respectivelyl Γt is a free boundarybetween Ω1(t) and Ω2(t).Let Ω=Ω1(t) ∪Γt∪Ω1(t)...In this paper we consider Verigin problem with surfaCe tension at freeboundary:where Ω1(t),Ω2(t) are regions of water and oil respectivelyl Γt is a free boundarybetween Ω1(t) and Ω2(t).Let Ω=Ω1(t) ∪Γt∪Ω1(t) be a bounded annular domainin R2, Ω2(t) is inside. nt is a normal of Γt, Pointing inwards Ω2(t),P1 and P2 arepressures of water and oil, μ1 and μ2 are viscosities of water and oil respectively, k isthe permeability, φ is the porosity, K and Vn are the curvature and the normal velocityof Γt in the direction of nt.We prove that the classical Verigin problem is the limit case(s-0) of Veriginproblem with surfaCe tension at free boundary.展开更多
The author considers Verigin problem with surface tension.Under natural conditions the existence of classical solution locally in time is proved by Schauder fixed point theorem.
