Flow Physics Modelling An Integrated Approach

The primary purpose: is to support the European aeronautics industry in the area of flow-physics modelling by bridging the gap between the most advanced research results in the area of turbulence modelling and their application in daily industrial practice.

The project is considered to be a unique attempt to group the best experts in research and CFD developers in Europe,
in order to transfer their advanced knowledge to the aeronautical industry in a controlled, objective oriented way.

To cope with the main aspects in flow physics, in particular in turbulence modelling, the following important issues are concerned:

1. Make the European industry benefit from the latest advances in turbulence modelling, from the point of view of reliability, robustness and accurate knowledge of the limitations of currently used algebraic, one and two equation, eddy viscosity, models.

2. Generate the validated integration of new non-linear and EARSM models in industrial aerodynamic CFD codes

3. Generate the validated integration of full DSM models in industrial aerodynamic CFD codes

4.Extend these implementations to the new generation of unstructured solvers, including the analysis of their impact on adaptivity.

5.Create the industrial transition process towards DES next generation of turbulence modeling

6. Establish the limits of validity of the various model generations for industrial applications

7.  Ensure a high level of focused technology transfer in implementation strategies of turbulence models into the industrial codes

In order to allow for a precise validation of the new models in currently used industrial methods, complex industrial test cases will be treated, even in case where property rights will not allow to distribute the desired geometry and/or test case. However, these complex test cases are of utmost importance for industry to demonstrate improvements in turbulence modelling in current industrial environments.

 Industry will receive support in implementation of models by partners involved in the development of turbulence models. Thus, the validation "weakness" due to different types of implementation into different codes will become obsolete -  to a certain extent strategically supporting EU policies on standardisation.

The innovative and challenging FLOMANIA project will aim, in accordance with the obtainable improved predictive accuracy in the area of aircraft aerodynamics, at robustness and reliability enhancements as well as an enlarged applicability domain which will definitely result in reduced simulation effort and corresponding design times and costs and will foster faster-time-to-market strategies. It should be noted that the latter, being of utmost industrial importance, will be fulfilled - despite a suggested per simulation increasing computation (CPU) time when using a full DSM turbulence model - because robustness, reliability and accuracy of the new approach will omit currently often  needed "re-runs" with (often) different turbulence models in order to reach a final (converged) result.

The project will generate a unique evaluation and synthesis effort towards a European "consensus" on the range of validity of advanced turbulence models, the best rules for their implementation, to be shared and transmitted in an organized way to industry. This integrative effort will considerably shorten the delay between advances in research and their industrial application.
