CFD Simulation of External Gear Pump using ANSYS CFX

摘要

Use CFD technology to analyze and predict external gear pump performance. In this paper, Experimental investigations were conducted on external gear pump with a 24 mm outlet pump diameter, suction pressure 2 kg/cm~2, speed 2500 r.p.m and flow rate 0.85 lit/min to assess the effect of various operating conditions like Head, Discharge, Power on the performance of the pump. Further the pump casing modeled using CATIA V5 software and computational fluid dynamics (CFD) analysis is carried out using ANSYS CFX software on the developed model of gear pump casing to predict the performance virtually and to verify with the experimental result of the pump and helps us rapidly to establish the efficiency of the pump over various operating conditions.
