Data driven technologies are revolutionising the engineering sector by providing new ways of performing day to day tasks through the life cycle of a product as it progresses through manufacture, to build, qualification test, field operation and maintenance. Significant increase in data transfer speeds combined with cost effective data storage, and ever-increasing computational power provide the building blocks that enable companies to adopt data driven technologies such as data analytics, IOT and machine learning. Improved business operational efficiency and more responsive customer support provide the incentives for business investment.&nbsp; Digital twins, that leverages these technologies in their various forms to converge physics and data driven models, are therefore being widely adopted.A high-fidelity multi-physics twin, HFDT, that digitally replicates a gas turbine as it is built based on part and build data using advanced component and assembly models is introduced. The HFDT, among other benefits enables data driven assessments to be carried out during manufacture and assembly for each turbine allowing these processes to be optimised and the impact of variability or process change to be readily evaluated.&nbsp; On delivery of the turbine and its associated HFDT to the service support team the HFDT supports the evaluation of in-service performance deteriorations, the impact of field interventions and repair and the changes in operating characteristics resulting from overhaul and turbine upgrade.&nbsp; Thus, creating a cradle to grave physics and data driven twin of the gas turbine asset.&nbsp;In this paper a HFDT of a power turbine module built with geometry taken from the manufacture and assembly process is presented. &nbsp;The process that involves simultaneous modelling of gas path and solid using high fidelity CFD and FE that converts the cold geometry to hot running conditions with no loss of hardware detail is used to assess the impact of various manufacturing and build variabilities.&nbsp; It is shown this process can be executed within reasonable time frames providing realisation of the vision and creation of a HFDT for each turbine during manufacture and assembly and for this to be transferred to the service team for deployment during field operations.

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
