About the Influence of Eco-Friendly Fluids on the Performance of an External Gear Pump

This paper wants to investigate the effects of eco-friendly fluids on thermo-fluid-dynamic performance external gear pumps in order provide a first response increasingly urgent demands green economy. A computational fluid dynamics (CFD) approach based overset mesh technique was developed for simulation full 3D geometry an industrial pump, including all characteristic leakages between components. sensibility analysis numerical model with respect different properties performed commonly used mineral oil, showing key role compressibility prediction pump volumetric efficiency. Moreover, influence temperature internal variations both density and viscosity were included. The BIOHYDRAN TMP 46 oil olive further considered this work, results simulations compared three configurations. slightly lower efficiency derived application against other two conditions, but suggestive improvements produced terms pressure distributions. Therefore, obtained results, encourages research activity towards use hydraulic field.
