Rolls-Royce Hydra CFD Code for Gas Turbine Engine Design
摘要
In 2012, Hydra became Rolls-Royce’s primary computational fluid dynamics (CFD) code for the aerothermal design of gas turbine engines used worldwide to power large commercial aircraft and for other purposes including power generation and naval propulsion. This article describes the history of its initial development at the University of Oxford, outlines some of its key technical features and the underlying mathematics, and discusses some of the engines developed using it. With its impact continuing today, Hydra was the basis of REF (Research Excellence Framework) impact case studies in both 2014 and 2021.
