Аннотация

The technique of inverse heat transfer is playing a significant role in many real engineering applications ranging from aerospace to industrial production processes. The operation, maintenance and quality control of various heat transfer processes occurring in many industrial applications often require accurate knowledge of boundary conditions, such as heat flux or surface temperature. In some situations, measuring these quantities is very difficult because of unapproachable locations or expensive instruments or tedious techniques. In recent years, however, the techniques of the inverse heat transfer problem (IHTP) have offered a convenient alternative to evaluate these quantities accurately, which significantly reduce the experimental resources. In this work, one inverse technique, ant colony optimization (ACO) method is used to estimate the spatially varying boundary heat flux of a furnace mould by employing the unique combination of predicting the characteristic profile and estimating the profile parameters using ACO optimization technique. This innovative technique and code is indigenously developed by the authors. There has not been any work done for the furnace applications using this novel inverse heat transfer technique.
