	Next-generation Filtration Systems Fleetgaurd (Cummins) Inc., Nashville, TN With air pollution on the rise and the EPA heading it off with strict regulations, auto manufacturers look to multiphysics modeling to take a serious bite out...
	Clearing the Air: Life Support for Space Exploration NASA Marshall Space Flight Center At the Life Support Systems Development Team, our task is to develop robust, life support systems for long duration space travel, such as lunar exploration...
	COMSOL Reveals How to Avoid Very Expensive Modifications to Wastewater Clarifier Witteveen+Bos, Deventer, The Netherlands A group of consulting engineers used COMSOL Multiphysics® and the Mixture Model application mode at a wastewater treatment plant to determine that simply...

	Laminar Static Mixer 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...
	Turbulent Residence Time in a Baffled Reactor 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...
	A 3D Model of a Diesel Particulate Filter 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,...
	Flow in a Bubble Column Reactor 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....
