| Aircraft engine as a kind of precise technology product,it needs in high temperature and high pressure,high speed and high load environment of long-term work repeatedly.Turbine blades as the working conditions of the worst parts in engine,put forward higher requirements for its design research.In order to design turbine cooling blade structures suitable for specific development objectives,researchers need to analyze a large number of blade temperature fields under different operating conditions and different blade structures,further carrying out turbine cooling blade design based on these analysis results.Currently,more and more people using the commercial CFD software to design turbine blades of fluid-solid coupling analysis,using the commercial CFD software to analysis needs not only engineers to master the basic theory of CFD software and operating method,but also a lot of effort for modeling,meshing and post-processing analysis.It improves the threshold of the users,and greatly increase the user workload.In this paper,based on SYSWARE.IDE engineering design platform,a specific three-dimensional fluid-structure coupling analysis and calculation system for turbine air-cooled blades is developed.The specific contents are as follows:Firstly,the relevant mathematical models and the underlying software tool models for fluid-structure coupling CFD analysis of turbine air-cooled blades are described.Then the overall system design and development plan are introduced,starting from the use of functional requirements,the system into the grid model,physical parameters setting,boundary setting,the solution set,the result post-processing and report five big modules,each module independently developed respectively.Each module can run independently,also can call each other,migration and data transfer.Then based on SYSWARE.IDE platform,the methods,formulas and experience accumulated in the analysis process of fluid-structure coupled are integrated into the system in the form of script files to optimize the fluid-structure coupled heat transfer analysis process of turbine blades.A fluid-structure coupling analysis and calculation template for turbine blades is formed through process construction and logic control.Finally,interface design,data association and system encapsulation are carried out to form a complete set of three-dimensional fluid-structure coupling rapid analysis system for turbine air-cooled blades.Combined with the evaluation of the developed system,can be found using the system greatly reduce the workload of turbine blades design analysis,compared with the traditional CFD software tools,through friendly concise design customized user interface,instead of the conventional tedious model CFD commercial software Settings and data input,can make the design personnel without through professional training.It can quickly master the operation of the system,and reduce the threshold for engineers to use CFD for blade temperature field analysis.Secondly,the numerical simulation analysis technology,calculation method and experience were integrated into the system platform during the development of the system,which optimized the fluid-structure coupling heat transfer analysis process of turbine blades.Finally,the system also has significant advantage in terms of computation period,using the system can obviously improve the efficiency of vane numerical simulation analysis,the designers have more energy into the higher accuracy of leaf development. |
