This analysis presents a refined method for added and coupling mass in fluid-structure interaction, indicating implications for seismic design and underwater dynamics.
The evaluation of added and coupling mass is central to fluid-structure interaction studies. Revisiting Batchelor's 1967 framework, this work introduces a refined approach based on superposition of acceleration fields and numerical evaluation of kinetic energy in potential flows. By distinguishing between added and coupling mass, the method clarifies inertial forces for diverse body geometries and highlights implications for seismic design, underwater dynamics, and multiphase flow modeling.
