Viscoelastic and Newtonian fluid transport in a ratchet geometry

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.
