Abstract :
In this research, the effect of gear tooth helix angle on external gear pump CFD characteristics is studied. Two different external gear pump models using spur and helical gears are simulated, and their pressure generation capabilities and pressure pulsation characteristics are compared. The monitoring points used for data analysis were placed at the high-pressure points of the pump, and iterative mathematical algorithms were applied for the analysis of the data. The results of this study showed that it was determined that the helix angle has a significant effect on pressure generation and the pulsation characteristics of the external gear pump. During general data regression and analysis, not only the comparison of spur and helical external gear pumps but also their pulsating values were investigated at different points in the flow domain, and their change intensity, results, and discussions were discussed in detail.
