Martin overestimates the minimum fluidization velocity in the case of the 210 μm particles, resulting in a sharp increase in predicted heat transfer coefficients only at a degree of fluidization of about 1.5. This is caused by the correlation for the estimation of the bed porosity that predicts porosities lower than the (measured) 45% at very low fluidization. To ensure a consistent use of the porosity correlation across all HTC correlations, bed porosity in Martin’s correlation was kept at a minimum of 45% to overcome numerical issues. See the methodology report in the repository for details. While Molerus is close to Grewals’s predictions in the case of the 87 μm particles, it is very far away in the case of 210 μm particles. This demonstrates the great discrep- ancies between correlations often encountered when trying to predict heat transfer in a fluidized bed. Figures 22 and 23 show the comparisons of the LINI and TRINI results to the different correlations: Ar . +18Re PDF Image | Heat Transfer between Finned Tubes
