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.
Learn how to improve reliability, durability, and safety for turbomachinery applications with high-fidelity aeromechanical simulations that account for blade flutter and forced response. The webinar also introduces a faster, streamlined workflow with advanced simulation capabilities, including:
Ansys Polyflow's unique mesh superposition technique (MST) capability makes detailed 3-D modeling of both single screw and twin screw extruders a reality. In this 20-minute webinar session, learn how you can make meaningful engineering decisions using a practical modeling approach. Understand the underlying assumptions and see sample outputs, including pressure distribution, temperature and shear rate.
Designing products, components and systems that can withstand a wide range of thermal scenarios is a design challenge that touches nearly every industry. From automobiles to high-speed semiconductors, thermal management concerns can often lead to wasted energy, reduced performance or premature device failure. This results in increased energy costs, warranty issues and additional design time that can reduce competitive advantage. To master thermal management design and truly understand thermal behavior of a system, streamlined multiphysics simulation tools are a necessity.
Take control of turbulence in your simulations with the GEKO (generalized k-omega) two-equation turbulence model in ANSYS Fluent. GEKO provides users with the flexibility to tailor turbulence models to their applications using several free and tunable parameters. These can be adjusted over a wide range to match the simulation to specific physical effects, while preserving the underlying calibration. This technical paper provides a detailed description of GEKO and includes best practices for use and optimization.
There is no single best turbulence model. Ansys believes in providing the widest range of turbulence modeling capabilities so the user can choose the right tools for the specific job at hand. While today’s CFD simulations are mainly based on Reynolds-averaged Navier-Stokes (RANS) turbulence models, it is becoming increasingly clear that certain classes of flows are better covered by models in which all or a part of the turbulence spectrum is resolved in at least a portion of the numerical domain. Such methods are termed scale-resolving simulation (SRS) models.

Engineers designing turbochargers face complex tradeoffs as they optimize their designs for cost, size and high transient response. One tradeoff involves sizing: a smaller diameter turbo is much better at reducing inertia, but does not generate as much pressure efficiently. Another involves efficiency versus manufacturability. The challenge is to balance these opposing design elements while delivering a wide range of speeds and flow rates, along with high efficiency across the turbocharger's operating range. View this webinar, and in 20 minutes you will learn how Ansys' multiphysics and optimization simulation tools — like Ansys TurboSystem including CFX — can help you perfect your turbocharger designs early in the product cycle.
