An Inverse Heat Transfer Approach for Evaluating Contact Interface Temperatures in Sliding Contacts

This research centers on the formulation and evaluation of a simplified inverse thermal analysis framework employing numerical techniques based on discretized elements. Experiments were carried out using Stainless Steel 304 (SS304) material to evaluate the effectiveness of the proposed inverse heat transfer technique. This study aims to evaluate the heat produced by friction at the interface of metallic surfaces under dry sliding conditions. Temperature data were collected at 3 mm and 7 mm from the interface using a pin-on-disk setup. The model integrates FEM with Beck’s algorithm for heat flux estimation. To validate the model predictions, transient thermal analysis was performed using ANSYS Workbench.
