Simulation approach to the fluid-thermal network and the application

A new approach combining fluid network and thermal network was developed to predict the characteristic of pressure, temperature and mass flow rate of engine. The simulated system was simplified into nodes and branches. Conservation equations were solved by a newly introduced fluid-thermal method. The program was validated by applying to the benchmark, and then the program was applied to predict the flow and heat transfer characteristics of turbine disk in engine, providing useful reference for design.
