“…In these equations, empirical correlations are included to describe the necessary transport parameters in order to meet measured conditions. There are different model depths and versions, which differ, among other things, in the flow calculation, the number of phases considered and the spatial dimensions.…”

“…Overall, cell models for the mathematical description of fixed‐bed reactors have not become established and have only been developed insignificantly since Adler's review . Stochastic models regard the processes inside a fixed‐bed reactor as random, whereby the probability of the respective phenomena occurring is determined individually. This kind of modelling is used very occasionally ‐ although it is not impossible to describe the random particle arrangement and flow distribution this way ‐ but the mathematical problem consisting of random functions with a fixed definition and value range is too complex to describe a fixed‐bed reactor completely. Particle‐resolved modelling means that the complex geometry of the reactor interior is taken into account and a full computational fluid dynamics (CFD) calculation is performed.…”

Modeling of heat and mass transfer in fixed‐bed reactors for heterogeneously catalyzed gas phase reactions is possible using different methods. Homogeneous and heterogeneous continuum models as well as particle resolved modeling of fixed‐bed reactors show high potential for application. Considering those approaches, advantages and disadvantages as well as underlying assumptions and boundary conditions are discussed. Additionally, methods for experimental validation are presented and discussed focusing on the two‐dimensional homogeneous models.

This article describes the fundamental procedure for designing fuel cell systems for vehicle applications, especially propulsion systems. It starts with the definition of the target specifications concerning vehicle performance, derived from the driving requirements of the customer. The design process of a fuel cell vehicle is repetitive and starts with a first vehicle concept, followed by the layout of drive train, where the requirements concerning fuel consumption, emissions, acceleration, top speed and climbing ability must be considered. The design procedure of the fuel cell system consists of the concept phase, the modeling phase as well as the simulation phase. The results, which include efficiency, emissions, turn‐down ratio, weight, volume, costs, cold start‐up time and heat rejection, are then compared with the original specifications. For a detailed simulation, input data and boundary conditions are necessary at the start, which can only result from the total design process — so these data have to be estimated before starting the layout process. The data found in the simulation of the fuel cell system are re‐used within the vehicle simulation. Analysis shows the sensitivity of the system concerning changes of a given technology and leads to the final definition of the design of all components of the drive system.

The integral reactor is most critical for experimental reaction engineering. However, its design does not come up to current requirements. Based on a tested modular construction principle, new modules for multifunctional integral pilot reactors with a wide range of applications were developed. These modules allow to configure both single and combination reactors for implementing varied methodical objectives. Two examples illustrate the advantages for the user.
