Abstract

The invention provides a continuous rotation detonation combustion chamber supercharge ratio predicting method based on a RBF neural network. The predicting method comprises the following steps: data sample acquisition, selection of input and output parameters, determination of the structure of the RBF neural network, training and testing of the RBF neural network and the like. The axial size, the peripheral size, the matching of inlet fuel / oxidizing agent flow, and total temperature and total pressure of an oxidizing agent of a combustion chamber are selected as input parameters of the RBF neural network, and the supercharge ratio of the combustion chamber is selected as an output parameter of the RBF neural network. By the predicting method, the specific mathematical relation between the input parameters and the output parameter does not need to be determined, the supercharge ratio of the continuous rotation detonation combustion chamber can be realized effectively, and the predicting method has a certain guidance significance on performance prediction of the continuous rotation detonation combustion chamber, the structural optimized design and modeling and simulation of a complete machine.

Description

technical field [0001] The invention relates to the fields of combustion, gas turbines and artificial intelligence, in particular to a method for predicting the pressurization ratio of a continuously rotating detonation combustion chamber based on an RBF neural network. Background technique [0002] With the intensification of the global energy crisis and the improvement of human awareness of environmental protection, how to achieve a substantial improvement in the performance of gas turbines is an important problem that needs to be solved urgently in the fields of aviation, ships and industrial power generation. Compared with the isobaric combustion used in modern gas turbines, continuous rotating detonation combustion has many advantages such as one-time ignition, small entropy increase, self-pressurization, and low emissions, and has become one of the most effective ways to improve the performance of gas turbines. [0003] The boost ratio is one of the important parameter...
