AIMing for Better Biomedical Devices

Earlier this year, we introduced ANSYS AIM, the first integrated and comprehensive multiphysics simulation environment designed for all engineers. Check out Richard Clegg’s recent blog post for an overview.

Since then, we’ve been applying AIM to a wide range of industrial applications, including the medical device industry, where AIM provides a modern, easy-to-use tool for a variety of applications. Continue reading

Aircraft Cabin Airflow: Curbing Disease Spread

For me, science and engineering has always been about designing solutions to the various problems in our everyday lives. When I began doing research in seventh grade, my very first project was a roof that converted the impact energy of precipitation into electricity to help power the home. The following year, I came up with a dynamically supportive knee brace that implements smart fluids to vary the amount of support that patients received, depending on the physical activity. Last year, I created a self-cleaning outdoor garbage bin to tackle the issue of urban sanitation in our neighborhoods.

This year, I tackled the issue of airborne pathogen spread in aircraft cabins, generating the industry’s first high fidelity simulations of airflow inside airplane cabins. Using my insights, I engineered economically feasible solutions that altered cabin airflow patterns, creating personalized breathing zones for each individual passenger to effectively curb pathogen inhalation by up to 55 times and improve fresh air inhalation by more than 190%.

Using ANSYS CFD to Analyze High-Lift Wing Design

Agastya ParikhFour years ago, as a high school sophomore, I began work on an independent project that explored ways to improve the performance of high-lift systems used on the Airbus A330-300. One of the biggest challenges facing me was how to best conduct experiments to assess the performance of the different designs. In prior years, I had conducted simple research on aircraft wing design and aeroelasticity using unpowered balsa models of the aircraft being tested. To employ this same method would be unworkable for the relatively complex systems of flaps and slats required by the Airbus aircraft. I would have needed to build a larger scale model or perform wind-tunnel testing — neither of which was viable because I did not have access to equipment of the complexity required. Continue reading

Landing Gear: An Aircraft System We Take for Granted

Watching the news recently I saw a video of an aircraft landing without one of its landing gear fully deployed. Wonderful job by the pilots and crew.

As it turns out, it is not that difficult to find other on-camera examples.

ASME Turbo Expo in its 60th year

2015 is a special anniversary year for ASME Turbo Expo: its 60th. This year the annual conference will be held June 15-19 in Montréal Canada, at the Palais des Congrès de Montréal. As in previous years,ASME Turbo Expo ASME Turbo Expo is the premier event on the international turbomachinery calendar. Besides gas turbine related sessions there are a host of others covering steam and wind turbines, compressors, turbochargers, fans and blowers, to name a few. Continue reading

Icing Again? Did I Miss the Summer and the Fall?

Looking back at my blogs this year, in February I talked about the ANSYS’ acquisition of the assets of NTI, Inc, which now enables us to offer the most comprehensive solution for integrated aerodynamic and icing simulations. The picture I shared was of a typical winter scene at a New Hampshire airport — the view of the de-icing process from inside an aircraft. Then in April, with Spring very much upon us, I talked about the upcoming event in Italy in partnership with CIRA. I am very pleased to report that this event went very well with over one hundred delegates and speakers from leading companies such as GE, Safran and Airbus. Thanks to all our speakers and to all who attended. So why do I think I may have missed the summer and the fall? Continue reading

A Better Automotive Paradigm

A hundred years ago, Henry Ford promised customers that their car could be painted any color so long as it was black. Today, color is the least of the auto industry’s challenges. The car of the 21st century must be fuel-efficient and robust, technologically savvy and affordable, and manufactured quickly on the line without defects. It must meet increasingly stricter government regulations. And the vehicle must incorporate fast-evolving electronic, communication and software technology that hardly existed a few years ago.

Accurate Spray-Wall Interaction Predictions with ANSYS Fluent 16.0

Computational Fluid Dynamics (CFD) has become an integral part of product design and development. Today, CFD is extensively used across industries like Aerospace, Automotive, Marine, Oil and Gas, Electronics, Health care, Process and Infrastructure. While CFD tools provide detailed engineering insights and shorter product development cycles at reduced cost, CFD community is constantly working hard to improve accuracy, speed and ease of use of these tools. Complex physical phenomenon such as detailed chemistry, primary atomization, electro-chemistry, icing formation are constantly investigated and newer, better and accurate numerical models are introduced in CFD tool.
