In this application, a solution is pumped through a catalytic bed where a solute species reacts as it gets in contact with the solid catalyst. The purpose of this example is to maximize the total reaction rate for a given total pressure difference across the bed, by finding the optimal ... En savoir plus
This example models a split-and-recombine mixer channel in which a tracer fluid is introduced and mixed by multilamination. Diffusion is removed from the model using an extremely low diffusion coefficient so that any numerical diffusion can be studied in the lamination interfaces. The ... En savoir plus
In this example, a simple ultraviolet (UV) water purification reactor is modeled using a combination of ray tracing, computational fluid dynamics, and Lagrangian particle tracking. First, the volumetric fluence rate is accumulated along rays released from the surface of the UV lamp using ... En savoir plus
This example simulates the heat profile in an air-cooled cylindrical battery in 3d. The battery is placed in a matrix in a battery pack. The thermal model is coupled to a 1d-battery model that is used to generate a heat source in the active battery material. The model requires the ... En savoir plus
This example shows how to set up a model of furrow irrigation in a nonuniform soil column. It employs the Unsaturated Dual Permeability feature, which links two Richards' Equations through a fluid transfer function. This scenario can be regarded as a benchmark problem for dual ... En savoir plus
Dielectrophoresis (DEP) occurs when a force is exerted on a dielectric particle as it is subjected to a nonuniform electric field. DEP has many applications in the field of biomedical devices used for biosensors, diagnostics, particle manipulation and filtration (sorting), particle ... En savoir plus
