The motion of transverse domain walls (DWs) in U-shaped ferromagnetic nanotube which owns two different geometric confinements were investigated by micromagnetic simulation. Driven by unidirectional magnetic fields, the chirality-dependent DW structure and velocity under low fields and two phases of chiral Walker breakdown processes under high fields were observable, respectively. All these chirality-dependent behaviors can be attributed to the different dynamics of magnetizations in geometric confinements. Additionally, DW structures have different responses and sensitivity to applied fields, leading to a hierarchy and complex Walker breakdown processes. This supplies a new perspective for manipulating DW chirality.
