Embodiment Construction

[0027] combine Figure 1 to Figure 4 Describe this embodiment, a double-wall cooling structure flow transmission system, by establishing a double-wall cooling structure flow transmission model, the final effect of the model is a flow transmission matrix I with a size of N×M N×M , the number of rows N is the number of impact holes, the number of columns N is the number of air film holes, and each element I in the matrix ij Refers to the flow rate transmitted from impingement hole i to gas film hole j. This model includes traffic automatic identification module, traffic priority matrix D calculation module and traffic transmission matrix I N×M Iterative correction module;

[0028] Such as figure 1 As shown, in order to realize the automation of the whole process, it is necessary to write a set of automatic traffic identification module, which can automatically open the numerical simulation result files (such as the cas and dat files of the numerical simulation results prepare...

Abstract

The invention discloses a double-wall cooling structure flow transmission system, relates to the technical field of double-wall cooling structure flow design, and solves the problems that in the prior art, designers need to have rich experience, human intervention is needed, an automatic optimization system separated from people cannot be constructed, and the like. The system comprises a flow automatic identification module, a flow priority matrix D calculation module and a flow transmission matrix iteration correction module. According to the method, the flow distributed to each air film hole by each impact hole can be calculated under the condition that the flow of the impact hole inlet and the flow of the air film hole outlet of the double-wall cooling structure are known. The flow path of the double-wall cooling structure is not restrained by the structure, but the fluid is automatically distributed under the condition that the inlet and outlet pressure is given, so that the flow distribution of the double-wall cooling structure cannot be calculated by a common fluid network method. The flow matrix clearly points out the directions of all fluids in the double-wall cooling structure, and the result can be used for effectively guiding the design of the cooling structure.

Description

technical field [0001] The invention relates to the technical field of flow design of a double-wall cooling structure, in particular to a flow transmission system of a double-wall cooling structure. Background technique [0002] The double-wall cooling structure combines the three cooling forms of impingement cooling, film cooling and convection cooling. Compared with other cooling structures, it has higher cooling efficiency and is an advanced cooling structure. The design of the double-walled cooling structure generally determines the structure of a cooling unit by selecting appropriate geometric parameters such as aperture ratio, hole spacing, and wall thickness, and then arrays the cooling units to obtain the final cooling structure. The above geometric parameters are achieved for higher cooling efficiency. The double-wall cooling structure designed in this way is highly repeated in different areas, and the flow distribution is relatively even, so that the cooling is in...
