Simulation of Microfluidic Devices Using COMSOL

Modeling and simulation form a systematic framework for developing and optimizing microfluidic systems. Such simulations often involve coupling multiple physical effects such as single- and multi-phase flow, mixing, dispensing, heat transfer, species transport and diffusion, chemical reactions, surface tension and wetting, electrokinetic effects, and flow interaction with biological material.

Products of Tomorrow: April 2015

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just some of the examples of NASA-developed technology used in products today. This column presents technologies that have applications in commercial areas, possibly creating the products of tomorrow. If you are interested in licensing the technologies described here, use the contact information provided.

Precision Measurement and Inspection Ensure Quality of SLS Rocket Panels

Reverse engineering and inspection software Verisurf Software Anaheim, CA 714-970-1683 www.verisurf.com In spaceflight, the first eight minutes are critical. This is when the greatest opposing forces of thrust and gravity are impacting the launch vehicle. The new NASA Space Launch System (SLS) will weigh 5.5 million pounds at liftoff, or roughly the weight of eight fully loaded 747 jets. Everything comes down to weight and the integrity of design and fabrication to insure success. Today, it costs $10,000 to send one pound of payload into orbit; since the entire launch vehicle makes the trip to low-Earth orbit, its net weight is a big consideration. The lighter the launch vehicle, the greater the payload can be.

Editor’s Choice

For 20 years, I’ve been interacting with engineers in all different industries as the Editorial Director of NASA Tech Briefs. I’ve talked with our readers about their work and the products they use. Many of them are CAD users, and many of them are unhappy with some aspect of their CAD software.

3D Printed Jet Engine Debuts

Researchers at Monash University in Australia have produced a 3D printed jet engine. Professor Xinhua Wu, head of the Monash Centre for Additive Manufacturing (MCAM), is leading initiatives to develop 3D printing. The Centre is working to provide answers for manufacturers seeking new manufacturing processes that make components lighter and cheaper than traditional ones, but without any reduction in performance.

Product of the Month: April 2015

Onshape, Inc., Cambridge, MA, introduced Onshape, the first full-cloud 3D CAD system with built-in data collaboration and management that lets all members of a design team work together using any Web browser, phone, or tablet. Using parametric and direct modeling techniques, the CAD system and data live in the cloud and are not copied, so everyone works on the same master at all times, eliminating checkouts, file copies, and overwriting. The product also eliminates installations, license codes and servers, service packs, and add-on PDM systems. Each user works on the same version of Onshape, so teams can access the same documents simultaneously. Access is controlled by the document owner, so each user sees visual indicators when others are working within the same document. Onshape allows users to perform all CAD work — not just view and markup — from a mobile device. The mobile apps are optimized for phones and tablets, allowing flexibility to access, collaborate, and edit CAD data anytime, anywhere, on any device. Both Free and Professional plans are available, with both providing access to full functionality. For Free Info Visit http://info.hotims.com/55588-120
