The development prospect of digital twin for the design of gas turbine
The traditional trial-design iterative method cannot efficiently support the design requirements of marine gas turbine,as the power requirements of ship navigation continue to improve.Digital twin technology aims to achieve the accur-ate mapping between virtual digital twin model and physical space gas turbine,which has the ability to supports the trans-formation of design system of gas turbine from traditional trial-design to digital design.In this study,the challenges existing in the design stage of gas turbine are discussed.The construction technologies of digital twin which contains a series of multi-fidelity and time-sensitive models are analyzed.The reduction methods for introducing high-dimensional models in di-gital twin are summarized.In order to form the closed-loop life cycle management of the marine gas turbine,the derivative strategy of the digital twin in the design stage is discussed.The key technology of dynamic performance adaptation is poin-ted out.On this basis,the research prospect of digital twin technology for the design of the gas turbine is prospected.
