Reduced Order Models (ROMs) for Simulation Democratization and Digital Twins

CFD analysis generally takes a long time and requires significant computational resources, which makes it difficult to perform real-time monitoring or predictive maintenance. In addition, prior knowledge/experience is required to set up CFD simulations and extract meaningful results. Reduced order models (ROMs) can significantly speed up the process and make simulations easier. A ROM is a simplified version of a high-fidelity computational model that preserves essential behavior and dominant effects while reducing the solution time and computational storage capacity required. In this webinar, a series of ROMs will be shown, along with the workflow to create the ROMs. These examples will highlight how ROMs can be used by operators/non-simulation experts to perform ‘what-if’ analysis within seconds without compromising on accuracy.

Aircraft Engine Icing

Recent events of high-altitude turbofan engine malfunctions characterized by sudden power loss and flameouts have been attributed to ice crystal formation in the compressor core. The understanding of ice accretion on rotor/stator blades is paramount and needs to be accounted for and integrated into the gas turbine design process.

Designing optimal anti/de-icing systems requires detailed understanding of complex icing phenomena and their interaction with air flow and ingested particles. Regulatory certification processes are often underpinned with expensive ice tunnel and flight tests with limited data points. High-fidelity CFD/icing models can help engineers develop a better understanding of complex icing processes and design better systems at a fractional cost.

ANSYS icing solutions empower engineers with high fidelity CFD/icing models to account for ice accretion and flow interactions early in the design phase in a seamless manner while harnessing the power of high-performance computing. Attend this webinar to get an overview of ANSYS icing solutions with a focus on ice crystal formation in turbomachinery compressors.

Accurate Prediction of Panel Flutter Applicable to Supersonic or High Lift Flight: Results and Comparison to NASA Wind Tunnel Data

Avoiding flutter of an aircraft's skin is important for safe and robust operation. Traditional panel flutter prediction tools fall short for conditions where the boundary layer thickness varies. ANSYS’ fluid–structure interaction (FSI) capability accurately predicts panel flutter under the most challenging conditions. ANSYS simulation results will be compared to NASA supersonic wind tunnel data. The simple simulation process and surprisingly small computational requirements for accurate results will also be summarized. Prime applications for the ANSYS FSI capability include next generation supersonic transports heralded by NASA's (X-59) low boom demonstrator or high lift flight conditions of subsonic aircraft.

Erosion Analysis in ANSYS Fluent

In this webinar, we discuss erosion modeling and erosion mesh deformation capabilities in ANSYS Fluent. Material erosion under a sand–liquid flow is a serious problem in many engineering applications, especially oil and gas. The ability to predict the progress of erosion in pipelines is critical. The erosion process is complex and often depends on many factors, such as fluid parameters, particle parameters, impact parameters and material parameters. Depending upon the pipe wall material and the solid particle, erosion could be high, leading to material loss and geometry deformation. In some cases, the shape deformation due to erosion can change the flow behavior and, as a result, the erosion rate. Thus, it is important to be able to model shape deformation.
