Abstract

The invention provides a turbine characteristic three-dimensional CFD automatic calculation method based on CFX software, and belongs to the technical field of turbine characteristics. The method comprises the steps of: employing CFX software to calculate a turbine design point working condition, and generating a turbine design point working condition result file; defining an outlet pressure initial value, a reference rotating speed and an initial rotating speed of the turbine; in an expression of CFX-Pre, defining a rotating speed expression according to the reference rotating speed, the initial rotating speed and the calculated cumulative iteration step number solved by CFX; defining an outlet pressure expression according to the outlet pressure initial value and the calculated cumulative iteration step number solved by the CFX; defining a turbine performance parameter expression in the expression of CFX-Pre; in the solver control setting of the CFX-Pre, setting a maximum iteration step number and a convergence standard; generating a set .def file in the CFX-Pre; and starting iterative computation by taking the turbine design point working condition result file as an initial field. The method is simple in calculation process and occupies fewer space resources.

Description

technical field [0001] The present disclosure relates to the technical field of turbine characteristics, in particular to a three-dimensional CFD automatic calculation method for turbine characteristics based on CFX software. Background technique [0002] Turbine characteristics refer to the change of performance parameters such as flow rate and efficiency of the turbine with the expansion ratio and rotational speed of the turbine. It can reflect the performance of the turbine under various working conditions and is one of the important basis for judging the aerodynamic design of the turbine. , which is also a necessary input condition for the engine overall professional to calculate the overall performance of the engine and the matching calculation of the performance of each component. Therefore, calculation of turbine characteristics is an essential part of the turbine aerodynamic design process. [0003] Turbine characteristic calculation can be divided into one-dimensio...
