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.
