Conductivity-Based Scheme for Identification of an Inner Pipe Boundary from Temperature Measurements

摘要

By solving two-dimensional inner pipe boundary identification problems, the numerical experiments have certified the feasibility and effectiveness of the presented computational scheme. The effect of the factors such as the initial guess and the temperature measurement error is negligible. Because no updating of the boundary shape is needed during the iteration process, the method is simple and timesaving; therefore, this computational scheme is very promising in the practical inspection and identification work. Of course, in the application, there are still many factors, such as the uncertainties in the boundary conditions and in the fluid temperature, that will also affect the identification results and that need to be discussed. This is our future work.
