Slow unsteady flow through a porous circular tube with axial waviness has been investigated by perturbing the solution for flow through a porous smooth tube. Waviness is assumed small in comparison to the smooth radius of the tube. Fourier transform technique has been used to get the expressions for axial and radial velocities and pressure. A particular case of sinusoidal waviness has been studied numerically.
