| الوصف: | Direct numerical simulations (DNS) of microscale fluid-structure interactions (mFSI) in multicomponent multiphase flows pose many challenges such as the thermodynamic consistency of multiphysics couplings, the tracking of moving interfaces, and the dynamics of moving triple-phase contact lines. We propose and validate a generic DNS approach: Diffuse-Resistance-Domain (DRD). It overcomes the above challenges by employing Onsager's principle to formulate dynamic models and combining traditional diffuse-interface models for fluid-fluid interfacial dynamics with a novel implementation of complex fluid-solid interfacial conditions via smooth interpolations of dynamic-resistance coefficients across interfaces. After careful validation by benchmark simulations, we simulated three challenging mFSI problems taken from different fields. Comment: 6 pages, 4 figures |
