The theoretical model of the windage resistance heating characteristics of the bolt structure in the rotor-stator cavity was analyzed. A numerical solution model for windage resistance heating characteristics of the bolt structure in the rotor-stator cavity was established to analyze the internal flow field characteristics of the rotor-stator cavity and study the influences of structural and operating parameters on windage resistance heating of the bolt structure in the rotor-stator cavity on the basis of verifying the accuracy of the solution model. The theoretical formula for windage resistance heating of the bolt structure in the rotor-stator cavity was constructed using the correction coefficient method. The research results indicated that when the bolt rotated with the rotating disc, the surface of the bolt interacted with the viscous airflow through friction, and the temperature of the gas increased, resulting in windage resistance heating effect. Under the working conditions studied in this article, when the speed increased from
