RÉSUMÉ
The cooling circuit of the exhaust diffuser in a reheated turbofan engine is studied by using a theoretical approach. Results are compared with experimental data obtained from both calibration rig and engine test bed. It is found that the analytical method provides good agreement with the measured data. Then, it becomes a powerful, but easy to use, design tool.
