Mathematical Modeling of the Working Processes in a Bicylindrical Spur Gear Pump
Two approaches to mathematical modeling of the working processes of a new design, a bicylindrical spur gear pump, are considered. The first approach is based on Bernoulli’s equation, Hooke’s law, and the laws of conservation of mass, energy, and the dynamics of motion. The k–ε model of turbulence is used in the second approach to model the working processes of the pump. A comparison of the use of the two approaches is conducted. A dependence of the instantaneous delivery of the pump on the rotation angle of the rotors is established.
