Özet
In this study, the numerical simulation of bed-to-wall heat transfer in CFBs is presented which based on previously developed 2D CFB model which uses the particle-based approach and integrates and simultaneously predicts the hydrodynamics, combustion aspects. The study is also validated with published data. The comparisons of the model predictions and experimental data indicate that the model is flexible enough to operate under different operational conditions concerning superficial velocity, particle diameter and suspension density values. Additionally, the simulation matches the measured data quite faithfully for heat transfer coefficient as a function of the suspension density at different temperature values which is also an indicator that that the simulation is valid for both cold and hot CFB units.
