Abstract

Estimation of unknown and/or uncertain boundary conditions encountered in thermal problems of continuous casting is considered in the paper. The boundary quantities are retrieved applying inverse techniques simultane- ously making use of temperature measurements at selected interior loca- tions. Such approach requires two step procedure. The first step is to solve a direct problem, or rather to derive the direct relationship between unknown boundary conditions and known temperatures at interior locations, while the second one is to stabilize the results of inverse calculations (inverse problems are usually ill-posed). The method used for solving a direct problem is the Boundary Element M
