Abstract:
As the heat transfer is based on physical processes which are expected to be deterministic, a major anticipation is that the experimental data should show good repeatability, if not reproducibility. In other words, it is expected that repetition of experiments with very similar inputs (bulk pressure and enthalpy, mass flow rate, heat flux …), should result in consistent and very similar outputs (heat transfer coefficient or inside wall temperature). However, comparable experiments with super...     »
