Inverse heat transfer analysis of multi-layered tube using thermal resistance network and Kalman filter

초록

In this study, a hollow cylindrical tube with a coating layer on its inner wall was considered. The thermal resistance network method was employed to solve the heat conduction in the tube. Unknown heat flux on the inner wall of the tube was estimated from measured temperature on the outer wall of the tube by the recursive input estimation algorithm consisting of the Kalman filter and real-time least squares. Assuming various operating conditions, the performance of the model developed in this study was evaluated.
