Influence of the outflow device shape on energy characteristics of the Turo-type torque flow pump

The paper studies the influence of two forms of outflow devices of the Turo-type torque flow pump with the high-speed running factor of 149 on its energy parameters. The devices were designed based on the accumulated research experience. The spiral outlet was designed taking into consideration the constant velocity moment in the design sections. Numerical calculation was carried out using the ANSYS CFX software package on the Polytechnic — RSK Tornado heterogeneous cluster of the Polytechnic super-computer center at the Peter the Great St. Petersburg Polytechnic University. Energy parameters of the torque flow pump having the studied high-speed running factor with the annular and spiral outflow devices were having the similar values.
