The influence is studied of several assumptions, often made in literature, on the values for the effective radial heat conductivity, wall heat transfer coefficient and overall heat transfer coefficient, as obtained from experiments in wall-cooled packed beds without a chemical reaction. Especially the choice of the inlet boundary condition can have a large impact on the values obtained. The influence of the presence of a radial velocity profile and also the cross-correlation of the parameters obtained is studied.
