The project aims at experimental data for the heat transfer of non-spherical catalyst particles in a fixed bed as a basis for model validation and development of new heat transfer correlations. For this, a new heat transfer test rig is be utilized. It appeared that the thermocouple holders for measuring the temperature profiles in the bed, and the inlet zone (where undesided backmixing took place) had to be improved. CFD modelling helped with this. Data from the current measurement campaigns depict a clear influence of particle shape on the temperature development in a bed. The measurements of beds with spheres are used to verify existing heat transport correlations. The measurements for non-spherical particle give scope for developing new correlations for heat transport in beds with non-spherical particles, and the measurements would also serve as reference for validation of particle resolved CFD models.
