Shape Optimisation of Displaced Enhancement Devices for Heat Transfer Augmentation by Inverse Problem Approach Applied to Infrared Images

摘要

Displaced enhancement devices are inserts, positioned inside pipes, with the aim of increasing the heat transfer rate. The actual work presents an original application of an inverse analysis technique to experimental infrared temperature data with the aim of estimating the local convective heat flux for forced convection flow in pipe when this kind of devices is present and, thanks to these results, with the aim of optimising insert geometry. In particular, butterfly-shaped inserts are investigated in terms of local and global thermal performances.
