THE USE OF NUMERICAL ANALYSIS IN ORDER TO HIGHLIGHT THE FLUID DYNAMICS INSIDE A HYDRAULIC GEAR PUMP MODEL

Abstract

An experimental method for the investigation of hydraulic fluid flow inside a gear pump model was performed during this study. The external gear pump model was chosen because this volumetric unit is capable to take over the fluid at atmospheric pressure at the inlet, to carry it through tooth gaps on the external walls and convey it further to the outlet at high pressure values. This volumetric unit type is the most commonly used in hydraulic medium power actuation because it shows a reduced complexity, a high reliability and easy maintenance in use. Due to specific structural solution, a gear pump transmits a constant fluid flow rate into circuit. This computational research will be used as an experimental method to study the fluid flow phenomenon inside different volumetric models used in the field of industrial hydraulic actuation.
