“…Buono et al [122,123] and, most recently, Shah et al [124] paid close attention to cavitation from physical modelling and experimental work in a particular gerotor pump unit. Buono et al [122] built a 1D-model by using the commercial software GT-SUITE ® , and Shah et al [124] introduced the cavitation prediction submodule in previous 'Generic Hydraulic System' presented by Pellegri et al [118,119]. More focused on monitoring cavitation conditions, a vibration technique was used by Buono et al [122,123].…”

“…Nevertheless, the selected contributions to the integrated approaches are Altare and Rundo [116] (the most comprehensive integrated method regarding the analysis of three commercial tools) and Pellegri et al [118] (the best integrated method regarding the comparison with experimental work). If a modelling of the cavitation phenomenon is pursued, the works of Buono et al [122] and Shah et al [124] have to be studied. Finally, the work of Pellegri and Vacca [121] is the successful contribution of considering the actual position of contact points between gears, as a function of the real geometric tolerances.…”

Over the years, numerous investigations have established the gerotor fundamentals. This work aims to provide a complete review of the literature from the last decade, focusing on the articles published in the past five years on gerotor technology in hydraulic machines. The report gives a catalogue of guidelines based on the trochoidal-envelope definition, a background analysis, the worldwide distribution of articles in each continent and country and the most frequently used keywords in the field. The paper identifies state-of-the-art research, and reports on current mainstream ideas. From the historical background, this literature review reports the current approaches in gerotor pumps (geometry and performance approaches, modeling and numerical simulations), orbital motors and new concepts. The report will serve as a guide and a directory for novel engineers working with gerotor technology in hydraulic machines. Another intention of this paper is to disseminate the works of the researchers who use this technology around the world, and to provide a scenario for future international collaboration. The paper gives an account of the disparity between academia and engineering applications. There is currently very little published literature on design and production methodologies for gerotor pumps and orbital motors. Hence, the future goal is to collect recommendations that combine academia and industry expertise to make better use of these extensive studies in the field.

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 methodologies used in the last years for the simulation of the flow rates generated by gerotor, external gear and crescent pumps. As far as the lumped parameter models are concerned, different ways of selecting the control volumes into which the pump is split are analyzed and the main governing equations are presented. The principles and the applications of distributed models from 1D to 3D are reported. A specific section is dedicated to the methods for the evaluation of the necessary geometric quantities: analytic, numerical and Computer-Aided Design (CAD)-based. The more recent studies taking into account the influence on leakages of the interactions between the fluid and the mechanical parts are explained. Finally the models for the simulation of the fluid aeration are described. The review brings to evidence the increasing effort for improving the simulation models used for the design and the optimization of the gear machines.
