The invention discloses a pipeline network method-oriented turbine blade fluid network visualization method. The method is a fluid network visualization method for a turbine air cooling blade pipelinenetwork method and can be used for mapping a three-dimensional topological communication network to a two-dimensional plane to generate a two-dimensional fluid network graph. Specifically, two-dimensional drawing coordinates of throttling elements and nodes are automatically planned according to input data such as communication relations and three-dimensional coordinates of the throttling elements in the turbine blade fluid network system; and finally the visualization of a turbine blade fluid network is achieved. According to the pipeline network method-oriented turbine blade fluid network visualization method, automatic drawing of the fluid network graph of the turbine air cooling blade pipeline network method can be achieved, the efficiency of the pipeline network method is improved, the period of turbine blade heat transfer calculation is shortened, and units and nodes in the generated network graph are arranged in order, the communication relations are accurate, and the drawing precision of the network graph is ensured.
Description
technical field [0001] The invention relates to the field of information technology, in particular to a visualization method for a turbine blade fluid network oriented to a pipeline network method. Background technique [0002] Turbine engines are widely used in aviation, ships, and large-scale engineering vehicles. The increase of the temperature before the turbine is an important measure to increase the thrust of the engine, and the temperature before the turbine is easily limited by the tolerance of the turbine blade material. Therefore, refining the cooling air and enhancing the cooling The cooling effect of the gas on the turbine blades is of great significance to improve the efficiency of the turbine engine. [0003] The pipe network method is the most commonly used method in the heat transfer design of air-cooled turbine blades. It refers to dividing the complex three-dimensional flow structure to obtain a series of "flow units" that meet the design requirements, con...
