A novel concept for the investigation and evaluation of radial heat transfer in tubular reactors in absence of a chemical reaction based on instationary measurements is presented in this work. Compared to known stationary investigational concepts one is able to get an increased informational yield from the experimental data especially for low tube-to-particle diameter ratios and small gas mass flow rates to be found typically in heterogeneous catalysis. The question discussed contrary in

A empirical correlation of the parameters for the two dimensional pseudohomogeneous model was found which allows a more accurate description of the experimental findings than known approaches from literature. The experiments were conducted for spherical particles and hollow cylinders made from steatite.
