For the conduction mode of heat transfer in a fixed bed, an evaluation of whether one of the most widely used equations for the stagnant overall thermal conductivity k_e^0, the Zehner- Schlunder cell model, is the most accurate and most efficient model in literature, was conducted. The equation was compared to a similar equation the Van Antwerpen. Multiple 1D Comsol Multiphysics models were constructed and analyzed for both set of equations. This data was compared to data from a three- dimensional computational fluid dynamics model or CFD model. These comparisons and data analyses established at least for now that the Zehner-Schlunder is still the best option when studying heat transfer in a bed, however further testing using other parameters is suggested.
