THE INFLUENCE OF THE MODEL SELECTED PARAMETER MEASUREMENT ERROR ON THE ACCURACY OF HEAT TRANSFER COEFFICIENT DETERMINATION METHOD FOR CONTACT BETWEEN ROLLS AND THE CAST STRAND

摘要

The paper presents a heat transfer model between two surfaces which are in contact under an external force. The developed heat transfer boundary condition model has been obtained using a new methodology for determining heat flux transferred between two solid surfaces. The methodology consists of two parts: experimental and numerical one. The experimental part involves measurements of temperature at specific points in two samples brought into contact. The numerical part uses an inverse method and the finite element method to calculate the heat flux at the interface.
