title = "Identification of the thermal resistance of the gas-gap between the ingot and mould in continuous casting of metals",
abstract = "The inverse approach for identification of thermal resistance of the gas-gap between the ingot and the mould during continuous casting of metals is the subject of presented paper. The least square adjustment method with {"}a priori data{"} is applied for identification of thermal resistance as well as the phase change location and the temperature field within the ingot and the mould. The results of temperature measurements at the number of sensors located in the wall of the mould are used to solve appropriate inverse problem and calculate the sough for thermal resistance. The front-tracking method with an automatic mesh generation finite element technique (so called deforming or moving finite-elements) for steady-state equation conduction-advection problems is developed to build the mathematical model of the temperature field in the ingot and the mould. Due to the strong convective nature of the boundary problem (casting velocity, thermal parameters) the special up-wind technique is applied. The validity of the solution of the inverse problem is checked by comparison with the solution of direct problem. Several numerical examples are presented and analysed.",
