Inverse estimation of heat flux and temperature in multi-layer gun barrel

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

“…For the validation, the present model was compared with a reference model employing the finite element method (FEM) along with the Kalman filter and recursive least-squares algorithm. The details of the reference model can be found elsewhere [22]. For both models, the initial temperature was T 0 = 298.15 K, the number of node elements was E = 25, the sampling interval was Dt = 0.001 s, and the exact transient heat flux profile was given as follows.…”

“…The details of the description and derivation of this algorithm can be found elsewhere [19,22]. The calculation process of the Kalman filter was expressed as follows.…”

“…In previous studies, the system modeling was conducted using the finite element method [19][20][21][22]. The finite element method expresses approximate functions from unknown variables and determines small element values using the weighted residual method.…”

A decentralized fuzzy inference method for solving the two-dimensional steady inverse heat conduction problem of estimating boundary condition

“…However, the inverse heat conduction problems (IHCP) can predict these parameters by utilizing measured temperature on or in the structures and have been applied widely [1][2][3][4][5][6].…”

Inverse estimation of temperature boundary conditions with irregular shape of gas tank

“…The maximum entropy method [6] is applied to estimate the surface temperature by Kim et al The inverse heat conduction problem is reformulated for MEM and a three-phase solution method using the successive quadratic programming. Chen et al [7] presents an input estimation method to estimate the time-varying heat flux and the temperature of the inner wall in the chamber recursively. Their simulated results show that the proposed method exhibits a good estimation performance and promotes a practical implementation highly.…”
