A phase-field method for interface-tracking simulation of two-phase flows
For interface-tracking simulation of two-phase flows, we propose a new computational method, NS-PFM, combining Navier-Stokes (NS) equations with phase-field model (PFM). Based on the free energy theory, PFM describes an interface as a volumetric zone across which physical properties vary continuously. Surface tension is defined as an excessive free energy per unit area induced by density gradie...
متن کاملA sharp interface method for incompressible two-phase flows
We present a sharp interface method for computing incompressible immiscible two-phase flows. It couples the Level-Set and Volume-of-Fluid techniques and retains their advantages while overcoming their weaknesses. It is stable and robust even for large density and viscosity ratios on the order of 1000 to 1. The numerical method is an extension of the second-order method presented by Sussman (200...
متن کاملA moving mesh interface tracking method for 3D incompressible two-phase flows
An interface tracking method using an unstructured moving mesh has been developed for simulating three-dimensional, incompressible, and immiscible two-phase flows. The interface mesh is moved in a Lagrangian fashion. A local mesh adaptation method is used to capture the changing interface curvature, maintain good mesh quality, and deal with large deformation. The interface is of zero thickness,...
