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.
