10 Simulation Advancements for Turbomachinery
More engineers trust ANSYS to provide robust, fast and accurate simulation solutions for turbomachinery simulation. Whether the simulation involves flow through blade rows for moving, compressing or expanding the flow; combustion physics; or supporting areas such as leakage flows, bypass flows or cooling flows, engineers use ANSYS CFD to go further and faster with well‐validated results across the widest range of general, specialty and multiphysics applications. ANSYS 17.0 greatly expands turbomachinery simulation capabilities in 10 ways across a broad spectrum to solve even more problems, improve results and enhance your ability to innovate.
- Improvements in memory efficiency and data handling have drastically improved speed and robustness when modeling combustion in ANSYS Fluent.
- The accuracy of reacting flows benefits from numerous physics modeling improvements, including support for all Chemkin reaction mechanisms, FGM models, soot modeling extensions, Eulerian wall film capabilities and evaporation physics. Advances in scale‐resolving turbulence methods provide higher fidelity results for combustion and other fluid flows.
Blade Row Modeling
- Fourier and Time Transformation methods solve multi‐stage transient blade row problems, including those with conjugate heat transfer, by calculating as few as one blade per row instead of the full wheel. This speeds time to solution by over 10x and drastically reduces the required computing resources.
- A breakthrough one‐equation intermittency‐based turbulence transition model widens applicability while reducing computational requirements.
- The Fourier Transformation method now solves multi‐disturbance (for example, gust analysis including upstream and downstream disturbances) and multiple‐frequency asymmetric flows (for example, a fan in a crosswind or an impeller in a vaneless volute).
- Aeromechanical simulation is extended with Forced Response Analysis for multi‐stage, multi‐frequency asymmetric and multi‐disturbance configurations. Enhanced numerics deliver more accurate blade flutter simulations.
- High‐Performance Computing advances deliver results with surprising speed for even the most computationally intensive turbomachinery applications.
- Simplified controls and improved workflow lead engineers to solutions faster and with less effort. You may output just selected data to monitor progress and simplify post‐ processing for very large simulations.
- A cooled turbine simulation with 1024 source points now delivers results 50 percent faster. Monte Carlo radiation models can now be solved at near theoretical maximum, double the previous speed.
Simulate the Whole System
- Only ANSYS can provide the tools needed to simulate every function of your turbomachinery. In addition to structures and fluids, ANSYS SCADE System Avionics Package for FADEC designers supports system design and software architecture. ANSYS 17.0 further increases productivity by fully integrating with the ANSYS Electronics Desktop and native Modelica support. It increases performance and capacity for electrified power systems in fields such as automotive, aerospace and defense, heavy equipment, and industrial machinery.
