Flow of a viscous liquid in a bent tube of finite length that undergoes deformation

A study is made of the closed flow of a viscous incompressible Newtonian liquid in a deformed tube with a section used as a peristaltic pump connected to a given hydraulic load. The time-average flow rate of the liquid (blood) in the external section is determined, together with the pressure difference across the load and the condition for the absence of hemolysis.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 2, pp. 177–179, March–April, 1981.
