- Abstract
- This talk introduces the audience to inverse heat conduction and presents some recent advances in this area developed by the UT Inverse Analysis Group. Inverse analysis is an emerging area due to its importance in the combining of measurements to engineering models. Inverse heat conduction involves the resolution of ill-posed mathematical models whereby discrete data is used to predict distant surface temperatures and heat fluxes. This projection process is nontrivial owing to the inherent instability associated with the ill-posed nature of the problem. Some discussion is offered illustrating the nature of inverse problems as well as a description of how the UT's Inverse Group resolves such problems based on the principle of global time. Several novel computational strategies have been developed producing accurate and stable predictions. Some representative examples will also be presented. Finally, both theoretical and numerical justifications are offered for promoting an alternative data form that would assist in resolving inverse heat conduction problems in a highly stable and representative manner. The development of a sensor that would deliver heat rate data would augment numerical simulations used by the inverse heat conduction community.
