Displacement of oil ( \(\pmb{\rho^{+}=1.1}\) ) by water ( \(\pmb{\rho ^{-}=0.86}\) ). (a) In an absolutely rigid solid and (b) in an elastic solid skeleton with the elasticity coefficient \(\lambda=15\). The contact points of the free boundary and solid body begin to move, and homogenization conserves the free boundary which separates the two liquids.
