 | Current research on methods to target chemotherapy drugs in the human body includes the investigation of biocompatible magnetic nanocarrier systems, for example magnetic liquids such as ferrofluids. This model investigates an external... |
 | In static mixers, also called motionless or in-line mixers, a fluid is pumped through a pipe containing stationary blades. This mixing technique is particularly well suited for laminar flow mixing because it generates only small pressure... |
 | Analysis of fluid flow into wells often begins with the assumption that the intake fluid is uniform along the entire length of wellbore. This assumption runs into trouble when applied to the modeling of perforated wells. When these wells... |
 | Large-scale reactors are usually made from stationary parts, often involving baffles. They make use of the baffled- imposed turbulence to provide mixing within the reactor. Yet, such reactors need to be optimized as too much baffling can... |
 | This model describes the simultaneous transport of three solutes in a chain reaction within a variably saturated flow field. Involved are advection, dispersion, sorption, biodegradation, decay, and volatilization.
The parent solute... |
 | In this example, drug-release from a biomaterial matrix to damaged cell tissue is modeled. Specifically, a nerve guide delivers a regenerating drug to damaged nerve ends. The model involves detailed drug release kinetics, with rate... |
 | Several factors influence a diesel particulate filter’s (DPF) efficiency and durability. Important issues include the removal of soot particles from the filter membranes and the influence of thermal stress on the ceramic structure,... |
 | Chemical vapor deposition (CVD) allows a thin film to be grown on a substrate through molecules and molecular fragments adsorbing and reacting on a surface. This example illustrates the modeling of such a CVD reactor where... |
 | Biotechnology is a rapidly growing area in the pharmaceutical sciences. One example of a clinical application is gene therapy, where it is possible to produce proteins in vivo, using the body’s own mechanisms for protein production.... |
 | This example illustrates multiphase flow modeling in a bubble column reactor. The reactor is filled with water and gas bubbles are injected from the bottom. Due to buoyancy, the bubbles rise, inducing a circulating motion of the liquid.... |
 | Removing halogen groups from hydrocarbons is an important reaction step in several chemical processes. One application is water purification. Other examples involve organic synthesis, where the removal of halogen groups serves as a... |
 | In fuel cell power generators, a steam reformer unit typically produces the hydrogen needed for the cell stack.
This example illustrates the modeling of a steam reformer. The reformation chemistry occurs in a porous catalytic bed where... |
