While seeking fast answers for customers, Chiyoda’s internal IT resources were too overtaxed to process large, complex simulations quickly. To create a more flexible IT infrastructure — and make the most of Chiyoda’s Ansys HPC Pack licenses — Ansys introduced Chiyoda to Fujitsu Ltd., a strategic partner offering cloud computing resources and expertise.
Engineers wanted to eliminate the use of thermal sensors on prototype engines by determining the heat flux with Ansys Fluent, then coupling Fluent to Rolls-Royce’s proprietary structural simulation code, thereby solving structural and thermal design problems simultaneously using an iterative process. But this solution required HPC, and HPC use at Rolls-Royce was at maximum capacity.
AG Furnace Improvements sought to increase the processing capacity of its crude heater, while maintaining optimal tube metal temperatures. Using Ansys Fluent, it analyzed the flame characteristics and temperature distribution within the heater to meet its design objectives.
Longevity and cost were a concern with the 3-D printed swirlers for a novel hot mix asphalt plant burner. Astec engineers performed design exploration using Ansys DesignXplorer, Ansys SpaceClaim, and Ansys Fluent to optimize the gas mixing tube design.
Cray and Ansys tackled the high-lift simulation challenge, working together on two high-lift prediction test cases developed by the AIAA CFD High Lift Prediction Workshop (HiLiftPW). The computational results — made possible by Cray XC supercomputing power and obtained with Ansys Fluent — showed excellent performance: a 189-million-cell simulation completed in under two hours.
In the aerospace market, there is a major push to move toward electric flight to realize a cleaner future, reduce operating expenses and produce more reliable machines. Annually, billions of dollars are spent by major airlines on fuel consumption strategies, and there is constant pressure from governments and society to find a better solution. As such, DuXion has set out to develop a highly efficient, light and compact electric propulsion unit for several aerospace applications that range from passenger aircraft to UAVs. However, to be competitive in this market, companies need to move fast and prove their ability to comply with a robust set of rules and regulations.
