The resistance characteristics of four positive multi-deformations at microscale were studied numerically with an inlet velocity of 1 m/s. The study involved four sizes of 0.04 mm, 0.06 mm, 0.08 mm, and 0.1 mm pipe inner tangent circle diameters to study the effect of circular pipe expansion boundary in this particular way. The common resistance characteristics among different pipes with the change of pipe diameter and inlet velocity are investigated. For the shape effect of different micro-pipes, the differences in the resistance stability characteristics with diameter and the inlet velocity change are analyzed in a new way, while the resistance distribution at the outlet is also analyzed. The results show the stability of the outlet velocity with pipe diameter changing is related to the shapes of pipes. Besides that, with a unique way to analyze the data, it is found that the positive-even polygon has a special distribution different from that of the integer-odd polygon, and a detailed way to describe the effects of different locations on resistance in pipes.
