Three?Dimensional Finite Element Modeling of a Viscous Fluid Flowing through an External Gear Pump

An external gear pump is a relatively simple and inexpensive pump, that used in variety of production systems. Numerous works have studied the using numerical simulations; however, typically low-viscosity fluids turbulent flow conditions are considered. Previous work authors focused on predicting output fluctuation volumetric efficiency an processing high-viscosity 2D representation. For certain conditions, backflow through all clearances could occur, resulting drop efficiency. This calls for full 3D model. Furthermore, high residence time zones observed inflow channel pump. The shape these still unknown. aim this to investigate effect axial performance A mesh generated by extruding third direction, prism elements. reduces required number elements therewith makes simulations computationally feasible. Introducing results lower compared simulations. With particle tracking, visualized
