Euler/Euler Modelling of Fluidized Bed Fluiddynamics,ystems. The solid phase is treated as a continuous fluid although it actually consists of many individual particles. Thus, the tangential and normal forces are represented by a solids viscosity and the so-called solid pressure. Furthermore, a model for the drag force between the phases is required.

Advantages of an Adaptive Method: The Simulation of a Fixed-Bed Reactor with Periodic Flow Reversalctor for exhaust air purification. The solutions are compared with regard to solution quality and computing time needed. It will be shown, that only the fully adaptive method will guarantee a sufficient solution quality.

Optimal Temperature Control of Semibatch Polymerization Reactors, those found in the speciality chemical processing industry. One of the aims in these processes is to keep a certain reaction temperature setpoint, in order to fit the quality requirements for the polymer..In the present paper, the optimal solutions of the underlying optimal control problems of the

Partitioning in reaction kinetics,ns are slow explicite methods can be used for the numerical simulation. Fast reactions, however, require the use of implicit methods. Very often there are only few fast reactions in a very large reaction system. Because of these few fast reactions the simulation has to be done with implicit integrat

Numerical Solution of Reaction-Diffusion Equations,ficient adaptation of the spatial and temporal discretization is often the only way to get relevant solutions of the underlying mathematical models. The corresponding methods are essentially based on a posteriori estimates of the discretization errors. Once these errors have been computed, we are ab
