This paper presents an improved method for time-domain modelling of transient laminar flow through tapered tubes. This method is based on the transmission line method (TLM), a technique using transfer functions and delays to calculate the pressures and/or flows at the ends of the tube. However, unlike previous methods that are limited to non-tapered tubes or are inaccurate at low frequencies, the method presented here is applicable across a wide range of taper ratios, dissipation numbers, and frequency content. The new model is compared in the frequency domain to a boundary value problem solution and in the time domain to a method of characteristics solution.

We provide a very general review of the resonant transmission line method for optical fiber problems. The method has been found to work seamlessly for a variety of difficult problems including elliptical and eccentric core fibers as well as “holey” photonic crystal fibers. This new version has been shown to offer great versatility with respect to cases of unconventional, inhomogeneous index profiles.
