On imposing dynamic contact-angle boundary conditions for wall-bounded liquid-gas flows

► Method is for wall-bounded incompressible two-phase flows with large density ratios. ► Method can handle both dynamic and static contact angle boundary conditions. ► Method reformulates Cahn-Hilliard problem into decoupled Helmholtz equations. ► Method de-couples computations for all flow variables. ► Method involves only linear systems with precomputable constant coefficient matrices.
