You may be surprised to learn that a standard passenger jet can have 30 to 50 antennas protruding from the aircraft’s external surface, producing drag forces that can drastically reduce fuel efficiency at a time when airlines are trying to reduce energy consumption. Most antenna designs are engineered for safety purposes, such as air traffic control, traffic collision avoidance, instrument landing systems and distance measuring equipment. Increasingly, antennas are being added to meet passenger demand for more and faster Wi-Fi access, in-flight TV and cellphone applications.
Antennas are mounted on the exterior of today’s airliners
It seems not all that long ago that I first attended the ASME International Gas Turbine Institute (IGTI) conference in Toronto. It was just a short drive from my office in Waterloo, Ontario. This year I took a much longer trip to Seoul South Korea to attend the ASME Turbo Expo. As I am already engaged in preparations for the 2017 edition that will be held in Charlotte, NC, I am reminded that much has changed in how rotating machinery is designed and operated. No doubt more evolution will be evident in the 2017 conference. One difference is that the conference will be held in conjunction with the ASME Power and Energy conference. I think that this makes a lot of sense, given the continued important role of turbomachinery in power and energy production and transmission. Continue reading
Energy systems innovation and sustainable design are key business initiatives in almost every industry sector. And, these initiatives are not only required to meet customer demand for “green products” or to satisfy environmental regulations. Many businesses have realized there is an opportunity to drive new growth with energy innovations. The new issue of ANSYS Advantage highlights the many ways our customers are delivering these energy innovations by leveraging the power of engineering simulation.
Turbomachinery can be the most rewarding of CFD simulations. At the same time, it can be the most challenging.
Turbomachinery covers a broad range of products including compressors, turbines (gas, hydraulic, steam, wind), turbochargers, pumps, fans and more. And turbomachinery users demand ongoing improvements, such as increased efficiency, reliability and durability while reducing emissions (for those involving combustion) and noise. Continue reading
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.

The recent drop in oil prices naturally has produced economic winners and losers, and price speculators and pundits are lining up conventional producers against those behind American-drilled Shale oil. Yet, questions remain about how the world is over-supplied with oil only a few years after we supposedly passed peek oil and survived oil prices topping $140 per barrel. Discounting the anticipated demand softness due to economic activities in Europe and Asia, technology is playing a strong role in finding, producing and using energy across the full range of industrial activities.

Hello all! My top engineering technology picks of the week include what to do with vacant World Cup stadiums, a jetpack that helps soldiers run faster and a system that could help cut down city traffic. Have a great weekend!
As a new member of the ANSYS family, via the Reaction Design acquisition, I thought I would take the opportunity to give you a little background on the product line I represent — CHEMKIN.
The software had its beginnings at Sandia National Laboratories, as part of the U.S. Government’s response to the oil crisis of the 1970s. Scientists at Sandia began studying how to make more efficient, cleaner-burning engines, and they created software to simulate the complex molecular-level chemical reactions that take place during fuel combustion. In 1997, Reaction Design licensed that software from Sandia and evolved the technology into a commercial-quality software suite that enables engineers and scientists in microelectronics, combustion and chemical processing industries to develop a comprehensive understanding of chemical processes and kinetics.

As we continue our 54.5 by 2025 blog series, we turn our attention to designing the body of the car for maximum fuel efficiency.

The body of the car provides two major opportunities for improving fuel efficiency:
- Reducing overall weight
- Improving aerodynamics to reduce drag
Much design work and ingenuity is required to reduce a car’s overall weight, and many interesting advances have been made in the field, such as the use of composites materials. Considering that car manufacturers have been working on streamlining and designing aerodynamics since the time of the Model T, we now need fresh ways to approach the issue.
The question is: What will be the most effective innovation, or combination of innovations, for the future?
Reduce weight by designing composites effectively
Replacing steel with light, strong and durable composites materials is one possible way of reducing weight in new automobiles. But the process has its challenges. Continue reading
While the auto engineering industry is undergoing a large breadth of innovation (autonomous vehicles, dashboard apps to help the driver use less fuel and drive more safely), the ambitious goal of 54.5 mpg by 2025 will require car manufacturers to focus on the fundamentals of existing technologies, such as engines, transmissions and aerodynamics.
Surely, 54.5 mpg is entirely achievable, but it is a daunting goal that will require auto makers to drastically ramp up their engineering efforts. And while 2025 seems far away, it will be difficult to finish all the necessary engineering by that time if engineers progress at today’s rate. Accelerating engineering is the burning need of the day — and of the next decade — and it can only be accomplished by taking full advantage of advanced engineering tools such as simulation.
