Prediction of the fate of inhaled fibres in human airways represents a significant challenge in comparison with spherical particles. There are several ways of computation ranging from a simplified approach assuming equivalent spheres with empirical corrections to sophisticated numerical solutions of momentum and rotations in three-dimensional flow. Each of these mathematical approaches has its area of application. However, their precision is still insufficient namely because of the lack of experimental data for validation. Especially data on the behaviour of fibres under transient flow in bifurcating channels is missing. This paper presents a description of the experimental setup for such measurement and statistically evaluated characteristics of the rotation and flips of micrometre-sized glass fibres. The results proved that there are significant differences in the rotations of fibres when compared to previously measured stationary flows.
