Using an oscillating ratchet geometry, an investigation of the
net fluid transport through the ratchet is undertaken in both Newtonian
and viscoelastic fluids. A detailed description of the numerical model
that couples the moving immersed ratchet structure to the bulk fluid
will be discussed. Numerical results presented will detail how
viscoelasticity enhances the net fluid transport in the ratchet.
