We are working on calculating the Overall Heat Transfer Coefficient of the packed bed

The following reference talks about the Overall Heat Transfer but calculates it from the wall Heat Transfer Coefficient.

A. G. Dixon, An improved equation for the overall heat transfer coefficient in packed beds, Chemical Engineering and Processing, 35 (1996) 323-331

But we are unsure about the "wall heat transfer coefficient"

Would love to have some input from you.

 

Not: we are not interested in using the Software as our specialized case does not fit with the software

Heat transfers from a hot material to a colder material. The interface between the two materials is the 'wall' where heat transfer takes place. Because the heat transfer causes a temperature gradient within the hot material and cold material, there is also heat transfer taking place away from the interface. The overall heat transfer coefficient of a packed bed depends on the characteristics of the materials involved in the heat transfer.

Sorry I must have mentioned it is an exothermic reactor.
