Examples stacked packing pressure drop

The literature abounds with references that are related to the study of convective heat transfer in packed beds. Although these studies have been primarily developed for ambient or warmer temperatures, the correlations that have been developed in terms of the Colburn factor or the Nusselt number versus Reynolds number are usually also applicable to low-temperature systems. For example, the heat transfer coefficient and pressure drop per unit length for a regenerator with a randomly stacked spherical-particle packing can be estimated from...
