TL;DR: A structured grid generation method is developed to generate mesh files required for CFD simulations of multi-lobe PC pumps and a numerical parametric study is carried out to investigate the effect of the number of lobes, the stator pitch, the circular fillet and clearance on the volumetric efficiency of PC pumps with viscous oils.

TL;DR: In this paper, a cylindrical vane pump with a 3.6% error between theoretical and simulation results is presented, which shows that the internal flow of the flow field is regular, the deformation is small, and the stress distribution of the main components is regular.
Abstract: The present article was to investigate the mechanical design, efficiency, and performance of a new type of cylindrical vane pump. The configuration is proposed on the traditional working principle of the hydraulic pump. The stator surface equations are driven by using the geometric theory of applied spatial triangulation function. The three-dimensional model of the cylindrical vane pump is established with the help of MATLAB, and Pro/E.A displacement formula is derived, which depends upon the design structure of the cylindrical vane pump. The flow output characteristics of the pump are analyzed. According to the kinematic analysis of the stator-cylindrical vane by Pro/Mechanism, the kinematic equation of the cylindrical vane is established and the kinematic analysis proves the effectiveness of structural design of vane pump. The CFD software COMSOL is used to simulate the force of the main parts under the different dynamic conditions, and the discharge flow of the pump are monitored. The result shows that the hermetic space is formed by the cylindrical vane, driving plate and the surface of the stator, and the size of the hermetic space is charged by the rotation of the cylindrical vane. The cylindrical vane pump satisfies the three elements design of positive displacement pump. The angle at the arc transition of stator surfaces is 5°–10°, when the number of cylindrical vanes increased, the flow pulsation of cylindrical vanes decreased and vice versa. There is a 3.6% error between theoretical and simulation results. The simulation result shows that the internal flow of the flow field is regular, the deformation is small, and the stress distribution of the main components is regular.
