A numerical calculation model with CFD porous media with friction heat as heat source was built. The temperature field of friction heat generation of brush seal used in a specific aero engine was analyzed. An experimental study of friction heat generation in brush seal with simulating operating conditions was conducted. A kind of technology using infrared camera was developed to get the real-time dynamic temperature field of brush seal. Experimental data was used to analyze and improve the numerical calculation model of heat generation. Based on these results

a stiffness correction factor was introduced and validated. During this study

a kind of calculation and experimental method validated by the experimental data was summarized

and could be used to analyze the temperature field of heat generation of brush seal in aero engine. Result showed that

by utilizing such methods

the error between calculation result and experimental data from simulated real operating conditions reduced from 48.15% to 10.67%.
