Gear pumps represent the majority of the fixed displacement machines used for flow
generation in fluid power systems. In this context, the paper presents a review of the different …

Low flow rate is one of the primary disadvantages of Roots pumps when they are applied in
hydrogen fuel cell vehicles. A novel profile for Roots pumps was developed in this paper to …

Hydraulic machines are faced with increasingly severe performance requirements. The
need to design smaller and more powerful machines rotating at higher speeds in order to …

The paper presents the computational fluid dynamics simulation of an external gear pump
for fluid power applications. The aim of the study is to test the capability of the model to …

This paper presents a three-phase fully compressible model applied along with an
immersed boundary model for predicting cavitation occurring in a two dimensional gear …

This paper proposes a new type of curve, an elliptical roulette, which it initially applies to
rotary lobe pumps. Once the new rotor profile has been mathematically modeled using the …

The flow in the suction chamber of an external gearpump is numerically analysed. The
evolution of the boundaries of the domain is very complex, and an arbitrary Lagrangian …

The paper presents a methodology for noise and vibration analysis of gear pumps and its
application to an external gear pump for automotive applications. The methodology …

The design of gear pumps and motors is focused on more efficient units which are possible
to achieve using advanced numerical simulation techniques. The flow that appears inside …

This study uses conjugate gear theory to mathematically model the cycloid rotor profile of a
Roots pump. After the rotor profile is generated based on the mathematical model of a rotor …
