| Abstract | In this paper, a multiscale method based on the combination of the Integrated Radial Basis Function (IRBF) approximation and the Brownian Configuration Field (BCF) approach is used to simulate the mechanical behaviours of flow of fibre suspensions. The bulk properties of flow including velocity and stresses are governed by conservation equations in continuum mechanics. Meanwhile the evolution of fibres’ configuration such as the position and direction of fibres are described by the Jeffery’s motion equation in the Eulerian form. The decoupled calculations at two different scales are linked together through the formula of stress by Lipscomb, by which the mutual influence between the kinematic properties of flow and the dynamic behaviours of fibres is represented. In this work, the IRBF based approximations are employed in two separate processes of the numerical discretisation. While the IRBF high-order approximations yield higher accuracy and faster convergence of the method, they might enhance the stability of the fibre dynamics simulation as well, especially for the case of concentrated fibre suspension. The validity of the method is demonstrated by simulating flows of different fibre concentrations between two parallel plates. |
