Four 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
Rotating machinery (or turbomachinery) is an application area that spans many industry segments. Each of these significantly influences the performance and efficiency of the entire system. Rotating machinery also covers a range of different scales from very large hydraulic turbines (10m diameter runner), steam and gas turbines to small automotive turbochargers that can fit roughly in the palm of our hand. Improving the performance of rotating machinery has long been realized as a crucial factor in the success of the system as a whole. Continue reading
This is the third year that ANSYS hosted the Automotive Simulation World Congress (ASWC), an international conference focused on engineering simulation in the ground transportation industry. The ASWC is an annual conference that rotates between the three major regions of the world. In previous blogs, I wrote about the 2012 and 2013 ASWC’s held in Detroit and Frankfurt respectively. This year the conference was held in Tokyo on October 9 and 10. Continue reading
The Chinese believe that you can’t be a true hero unless you climb the Great Wall of China. As someone who yearns to be a hero in everyone’s eyes, (much less the eyes of 1.3 billion Chinese folks), I set out to conquer the wall earlier this month during a vacation to Beijing, Xi’an and Hong Kong.
First, a grossly abbreviated history of the Great Wall: While several small walls were constructed as early as the 8th century BC, it was Qin Shi Huang, considered the first emperor of China (and the body protected by the equally amazing terracotta warrior army), who devised a large wall to protect his territory from northern invaders. With the help of several other dynasties, the wall was modified over several thousand years, leading to a modernization effort by the Ming Dynasty in the 14th century. Continue reading

During October’s Engineering Simulation for Military Technology Conference, just outside Washington, D.C., there was much discussion of the tools and techniques for simulating the depth of the design V — from requirements planning, through system of systems, through systems to full physics-based simulation. A clear standout theme from the presentations and interactions was an increasing convergence of these different scales of tools. From the top level there is downward pressure to incorporate increased fidelity in the models used to support the systems view and that this needs to be derived from a physics-based understanding. From the lower levels there is upward pressure to extract physics-based reduced-order models and robust design envelopes that can be used to feed into higher-level systems models. This is moving beyond the realm of discussion and is becoming reality. One example of real-world application is the use of physics-based simulation to develop better helicopter flight simulators — in effect simulating the simulator! Watch and listen to the team at the University of Liverpool in the U.K. talk about this work.
