Abstract

To predict the behaviour of a shell and tube heat exchanger it is imperative to determine the conditions existing within the shell. This is especially critical if leakage between shell and baffles and between shell and tubes exists, which holds in most of the practical cases. However, technical limitations do not allow for making these measurements without disturbing the actual conditions. In this work an experimental rig was developed, which would only negligibly disturb the actual flow and heat transfer conditions. Additionally it has the flexibility to allow for pressure and temperature measurements along each tube in the shell, practically at any desired position in axial direction. Moreover number of segmental baffles can be varied as desired. The results have shown that behaviour of temperature and pressure profiles is well in accordance with th
