Abstract

This application provides a method and apparatus for predicting the heat transfer performance of a compressor disk system. The method includes modeling a compressor to extract a compressor disk model from the obtained compressor model; discretizing the compressor disk model into multiple interconnected functional units, wherein different functional units represent component regions or fluid regions within the compressor disk system formed by the coupling relationships between different components; constructing a network topology diagram of the compressor disk system based on the above multiple functional units, and establishing conservation equations for the nodes and edges in the network topology diagram, wherein the nodes in the network topology diagram represent the state parameters to be solved, the edges represent the fluid flow information or heat transfer information between different nodes, and the conservation equations represent the conservation of heat transfer, flow rate, or temperature of the nodes or edges; and using a processor to jointly solve the multiple conservation equations to obtain the heat transfer prediction information of the compressor disk system.
