Experimental and numerical investigation on inspiration and expiration flows in a three-generation human lung airway model at two flow rates

•The mainstream flow behaves as skewed, double-peaked and M-shaped patterns.•The secondary flow behaves as Dean-type two-vortex, four-vortex, six-vortex and eight-vortex patterns.•The respiratory flow patterns are heavily influenced by the combination of geometrical bifurcating/merging, local wall c...
