Estimation of Heat Transfer Coefficient Obtained During Immersion Quenching

摘要

The estimation of thermal boundary conditions occurring during heat treatment processes is an essential requirement for characterization of heat transfer phenomena. In this work, the performance of four optimization techniques is studied. These models are the Conjugate Gradient Method, the Levenberg-Marquardt Method, the Simplex method and the NSGA II algorithm. The models are used to estimate the heat transfer coefficient in ID and 2D axis symmetrical cases during transient heat transfer. The performance of the optimization methods is demonstrated using numerical experiments.
