Abstract

<jats:title>Abstract</jats:title><jats:p>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.</jats:p><jats:p>The effect of uncertainty of input parameters for the calculation of heat transfer coefficient has been analysed. These have included: thermal conductivity, specific heat and location of thermocouples. Verification calculation with new value of input parameters for their impact on the accuracy of the solution has been done.</jats:p><jats:p>The calculations have been performed using original software which uses the inverse method and FEM.</jats:p>
