	COMSOL Reveals Unknown Effects in Process Instrumentation MKS Instruments, Wilmington, MA Modeling has become invaluable in MKS Instruments' development of first-class mass-flow controllers for the process industry. They have gained a detailed...
	MEMS Biosensor Brings about Disposable DNA Detectors Dept. Mechanical Engineering, University of California, Santa Barbara, CA Wouldn't it be a great service for the diagnosing and treating genetic of diseases if physicians had a disposable instrument for detecting DNA that worked as...
	Simulation Addresses Band-Broadening in HPLC Systems Waters Corp., Milford, MA, USA At Waters Corp., people who work in R&D have seen a lot of benefits from doing simulations — from understanding fundamentally what happens to...

	Micro Mixer The development of mixers does often not only have to account for effectiveness, but also other factors must be involved, such as cost and complexity for manufacturing. This example studies a laminar static micro mixer with two...
	Inkjet This example demonstrates how to model the fluid flow from an inkjet, for instance, within an inkjet printer. An ink droplet is ejected through a nozzle and travels through air until it hits the target. A conservative level set method...
	Hydrocarbon Dehalogenation in a Tortuous Microreactor 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...
	Fully-coupled Physics with Joule Heating, CFD and Chemical Reactions In this example, a fluid carrying several chemical components is pumped into a detector compartment. A wire in the center of the detector is heated through Joule heating, which is supposed to detect changes in density through convective...
