Abstract

This paper simulated the microscopic flow in a fiber bundle using the moving particle semi-implicit (MPS) method. Two phases (resin and air) were directly modeled to clarify the detailed mechanism of air entrapments in a fiber bundle. An external force was then introduced into the Navier-Stokes equation using a quasi-potential term to express the wettability between fiber and resin. To validate the MPS method for application to resin flow, we simulated a droplet of resin. To validate the present approach, we simulated silicone oil-and-air two-phase flow and compared the simulation results with experiment results. The simulated results for silicone oil flow agreed well with the experiment results. Based on these validations, resin-and-air two-phase flow in a fiber bundle was simulated to analyze void formation in a fiber bundle.
