Mechanical Models for Tubular Reactor Fuel Elements

Equilibrium Profiles of Tubular Reactor Nonlinear Models

The multiplicity of the equilibrium profiles is analyzed for axial dispersion nonisothermal tubular reactors described by Arrhenius type nonlinear models. It is reported that there is at least one steady state among the physically feasible states for such models. Moreover physically meaninful conditions which ensure the multiplicity of equilibrium profiles are given.

Development of Tubular Chemical Reactor Models for Control Purposes

A generalized nonlinear mathematical model for fixed-bed tubular chemical reactors with cooling is proposed. The model is suitable for simulation experiments. A strategy, focused on simplifying and adapting the "primary" model to control applications is shown. This procedure is driven through the so-called "pseudohomogeneous" form of the model until a final description which is linear and relat...

Mechanical models for the self-organization of tubular patterns

Organogenesis, such as long tubule self-organization, requires long-range coordination of cell mechanics to arrange cell positions and to remodel the extracellular matrix. While the current mainstream in the field of tissue morphogenesis focuses primarily on genetics and chemical signaling, the influence of cell mechanics on the programming of patterning cues in tissue morphogenesis has not bee...
