Finite element method for a fluid flow in a non-uniform channel
A numerical method based on the fnite element method is used for an investigation of
viscous, incompressible fuid fowing in a channel with slowly varying cross-section
with absorbing walls. The proposed mathematical model can be applied to understand
the fow behaviour of a fuid in renal tubules. The method is not restricted by the
parameters in the problem such as wave number, permeability parameter, amplitude
ratio and Reynolds number. The effects of these parameters on the transverse velocity
and mean pressure drop is studied and the results are presented graphically. Results
show that the parameters cause a signifcant change on the fow
