Numerical Simulation of Bubble and Droplet Dynamics using Partitioned Solvers

Bubbles and droplets can be simulated as a problem involving Fluid-Structure Interaction (FSI). The interface between the liquid and the gas is then conceived as a zero thickness structure. The position of the interface is determined by the equilibrium between surface tension effects and the pressure jump across the interface. Most techniques...

Strong coupling of partitioned fluid-structure interaction problems with reduced order models

The paper describes a new and powerful technique to solve strongly coupled fluid-structure interaction (FSI) problems with partitioned solvers. In order to achieve strong coupling approximate Jacobians of the fluid and structural solvers have to be known. In the proposed method the response to applied displacement and pressure modes are used to...
