Embodiment 1

[0020] The invention discloses a method for obtaining modeling parameters based on data correction in the one-dimensional centerline design process of turbomachinery. Data import and data import provide two methods: (1) Use "select parameters" to specify the parameter names available for test data , then set the number of points for the data point. This option requires the user to enter all data in each cell. ②Allow users to import data from Excel CSV files in a predetermined format. When you try to import the data file, the program requires you to match the user variables with the variable parameters in the program. After completing the above operations, the program can import user data with the correct unit conversion ;Run the data correction and click the "Run" button. After the operation is successful, all the data and the corrected modeling parameters will be saved in the example file; when running the calibration analysis model and running the multi-point analysis module...

Abstract

The invention discloses a method for obtaining modeling parameters based on data correction in the one-dimensional center line design process of turbomachinery. By using higher-precision data, a calibrated analysis model is obtained after calculation and analysis, the machine performance of the model or other models with pneumatic similarity under the design and non-design working conditions can be predicted, and the method has the advantages of being accurate in prediction, high in efficiency, short in period and the like. Compared with the prior art, the method has the advantages that (1) aconvenient and friendly interface is provided, and a user can conveniently import data; (2) the speed of a one-dimensional centerline analysis program is high, and modeling parameters can be quickly adjusted to match target data; (3) the machine performance prediction based on the data correction is more accurate, and is more suitable for the actual situation; and (4) the data comparison operationis simple and the graphical representation is visual.

Description

technical field [0001] The invention relates to the technical field of turbomachinery design analysis, in particular to a method for obtaining modeling parameters based on data correction in a one-dimensional centerline unit of a CAE integrated platform. Background technique [0002] Turbomachinery is widely used in chemical, metallurgy, coal, petroleum, electric power, national defense, light industry, agriculture and civil sectors. Turbomachinery software, as an important foundation and core support for intelligent manufacturing, plays an important role in improving the efficiency and performance of machines. Guiding significance. [0003] In the current one-dimensional centerline design process of turbomachinery, the designers of many related enterprises and research units usually use the existing slip and loss models to design and predict the performance of the machine. The results are as follows: : [0004] 1. Use the calculation of some empirical formulas in the text...
