A group of consulting engineers used COMSOL Multiphysics® and the Mixture Model application mode at a wastewater treatment plant to determine that simply... |
Example Models
 | In static mixers, also called motionless or in-line mixers, the fluid is pumped through a pipe containing stationary blades. This mixing technique is particularly well suited for laminar flow mixing since it gives small pressure losses in... |
 | A key optimization parameter in a fuel cell is the design of the reactant and product channels and inlets and outlets. Good designs require that the electrodes are well fed with a reactant and that products are removed as quickly as... |
 | 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 presents a study of the current density distribution in a solid oxide fuel cell (SOFC).
The model includes the full coupling between the mass balances at the anode and cathode, the momentum balances in the gas channels, the... |
 | 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.... |
 | Wastewater treatment is a several-step process for removing contaminants. Firstly, large, solid particles are removed through sedimentation, flotation, and filtration. And then in a second step, biological treatment causes the smaller... |
 | 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... |
 | Freeze-drying, or lyophilization, is a process for drying heat-sensitive substances such as foods, blood plasma, and antibiotics. The wet substance is frozen and then through sublimation ice or some other frozen solvent is removed in the... |
