Title:
Numerical calculation of wall-to-bed heat transfer coefficients in Geldart B bubbling fluidized beds with immersed horizontal tubes 
Abstract:
In dense solid-gas fluidized beds the knowledge of the wall-to-bed heat transfer is of great importance, since it often dominates reactor design and dimensioning. This heat transfer is strongly coupled to the hydrodynamic behavior of the bed material around the immersed objects. In this study the heat transfer coefficient at horizontal tubes in a Geldart B bubbling fluidized bed is determined experimentally and compared to the numerically predicted flow fields. The objective is to improv...    »
