METHOD OF COUPLED NUMERICAL SIMULATION OF FLUID-STRUCTURE, AND STORAGE DEVICE PROGRAM FOR COUPLED NUMERICAL SIMULATION OF FLUID-STRUCTURE

摘要

PPROBLEM TO BE SOLVED: To provide a method of coupled numerical simulation of a fluid-film structure that can compute interaction problems between the motion of a film structure changing with time and the motion of a fluid flowing on the surface by a simple technique on the same program. PSOLUTION: For simulating fluid-structure interaction phenomena where, in the process of applying a liquid on a film, the discharged liquid behavior changes the position and shape of the film surface and the liquid flows on the surface, the method performs a fluid analysis and a structure analysis in a single solver on the assumption that the film surface is a solid area surface in computational meshes, and simulates the movement of the film surface of the film structure in each computational time step from the balance between pressures acquired by fluid computations of the fluid 21 and reactions acquired from the tension and curvature of the film structure on the assumption that the film structure 18 does not have rigidity against bending.
