On Web Digital Twins: an use case for a Gerotor pump

In the current wave of digital industry, Digital Twins play a major role in the virtualization of manufacturing processes. Digital Twins are virtual entities that mirror the behavior of physical entitites. They are used to predict or monitor the information of a product or a process. In recent years, virtualization technologies have benefited from cloud computing and web-based services to enhance the capabilities of industrial Digital Twins. These Web Digital Twins enable greater degree of distribution and collaboration between the users of the Digital Twin. In this article we present an use case of web-based Digital Twins for the design and monitoring of Gerotor pumps. The novelties of the present article are: i) it highlights the advantages that result from applying the Digital Twin methodology to the case of Gerotor pumps, ii) it describes the implementation of a web-based Digital Twin tool for a Gerotor pump. Our tool allows the user to design a Gerotor pump using a parametric interface, visualize the 3D model of the pump, visualize its expected performance using fast simulation routines and obtain the optimum design for a set of desired performance parameters. This article focuses on the technological overview of the Digital Twin tool and its web-based architecture, as the simulation and optimization details were addressed in different publications.
