Numerical prediction of the fiber orientation in steady flows
Keywords:
short fiber reinforced thermoplastic flow, transport equation, method of characteristics, SUPG finite elements method, discontinuous finite volumesAbstract
Modelling fibers orientation induced by the flow of short fiber reinforced thermoplastic involves a classical anisotropic Stokes flow problem and a hyperbolic orientation equation. This paper aims to achieve a comparison between different solution techniques suited to the hyperbolicity of the orientation equation (viz. the method of characteristics, the SUPG method and the discontinuous finite volume method).
