Simulating the motion of flexible pulp fibres using the immersed boundary method (Q1287234)

We demonstrate how the complex hydrodynamic interaction between a flexible fibre and the surrounding fluid can be simulated using the immersed boundary method. The computations involve a single fibre suspended in a two-dimensional shear flow at moderate Reynolds number. The computed fibre orientation angle distributions are compared to classical theoretical results and shown to exhibit a skewness which is not captured by either the linear theory or other recent numerical computations that ignore the fibre-fluid interaction. \(\copyright\) Academic Press.
