Noordwijkerhout, Netherlands, 26-31 may 2013.This work presents an experimental study to determine the capacity of a Phase Change Material (PCM) in granular form to be used in a bubbling fluidized bed for thermal energy storage. The experimental measurements are focused on the determination of the heat transfer coefficient between a heated surface and the granular PCM in fluidized state. The results obtained indicates that the heat transfer coefficient notably increases (up to values three times higher) when the granular PCM is in solid form because it changes its phase when touches the heated surface8application/pdfeng© 2013 Engineering Conferences Internationalconference proceedingsFísicaIngeniería Industrialopen access14th International Conference on Fluidization 2013: From Fundamentals to ProductsCC/0000021882
