New methods for prediction of detached flows

EU-funded scientists collaborated with the aircraft industry to understand the underlying physics of detached flows and develop new methods and solutions.
New methods for prediction of detached flows
In the frame of the ANADE (Advances in numerical and analytical tools for detached flow prediction) project several European universities, research centres and big companies collaborated to train early-stage and experienced researchers in every aspect concerning the prediction and control of detached flows. In addition, the project aimed at a better understanding of the underlying physics and development of new dedicated numerical methods.

Flow separation phenomena were approached on the basis of four complementary work packages. These combined efficient numerical methods, receptivity, sensitivity and instability analysis, uncertainties and mesh algorithms, and computational aeroacoustics.

The project encouraged the exchange of expertise from inside and outside the network team and communication between industry and academia. Related efforts led to joint publications and advances.

Developments included adaptation strategies on truncation error or adjoint methodology and new generation of meshes adapted to complex geometries and curved boundaries. Furthermore, the team implemented the first prototype industrial high order solver and updated stability analysis to complex geometries and turbulence models. They also posed and obtained preliminary results on the mathematical formulation of the sensitivity of the flow under external perturbation.

The final project results led to 32 publications, proceedings and book chapters in international journals and forums. Additionally, the project organised a related one-week lecture with more than 50 attendees and an international workshop.

ANADE managed to successfully train highly qualified individuals and produce new initiatives and synergies, enhancing also high-profile research in aeronautics between European countries. Moreover, 12 PhD candidates used the results of their work during the project, which will help establish strengthened partnerships among universities, research centres and industry.

As a consequence, industry benefits from ANADE by being kept up to date on the latest technologies and implementation possibilities within the design process. The new techniques enhance the analysis of flow separation and noise generation, and afford novel simulation methods and solution quality increase.

Project outcomes are of great importance for the development of technological innovations in the aircraft industry. ANADE results may serve for future performance enhancement of aircrafts and contribute to reduced environmental impact with regard to air and noise pollution.
