Mathematical models have been developed to describe Supercooled Large Droplets (SLD) or Snow behaviour and features such as follows:
• Splashing, bouncing, and re-emission phenomena for SLD (WP9 activities)
• Drag, melting, sticking, or erosion for snow (WP10 activities).
Also, automatic 3D remeshing processes have been developed in the work package 9.
Its outcomes have been tested in the work package 11. The activities were split into 3 parts:
• Task 11.1: Validation of App C numerical capability in industrial environment
• Task 11.2: Validation of App O numerical capability in industrial environment
• Task 11.3: Validation of Snow numerical capability in industrial environment
For each task, the work carried out is summarized below:
• Update the in-house tools of the industrial partners with the numerical models developed in the work package 9 or 10
or
transfer the tools from the academic partners to the industrial partners and integrate them in the industrial environments.
• Perform simulations and validate the numerical models on:
o Common test cases (defined for each task). They had to be simulated by each industrial partner involved in the task.
o Industrial test cases (one or several), like 3D swept wing or engine inlet (only for liquid icing).
• Define best practices related to the use of numerical tools.
To achieve these objectives, the activities differed according to the nature of the partners involved.
1. Academic partners activities:
Their activity consisted in supporting the activities of industrial partners using their tools. Technical support was provided to install simulation tools in industrial IT environments. They also supported them to solve potential difficulties during the simulations.
2. Industrial partners activities:
After simulations, the first activity was to cross-check the results from the different computational chains. All industrial partners had to ensure that they had simulation tools with a level of maturity at least equivalent to those delivered in WP9 or WP10. Moreover, each partner had to define the best practices associated to their tools to ensure an appropriate level of accuracy and robustness.
The second activity was to validate the numerical tools on test cases representative of industrial applications: engine inlet, 3D swept wing or rescue hoist. These activities were necessary to assess the level of maturity of the tools (TRL) and confirm that the tools meet the needs of industrial partners.
Lastly, the industrial partners provided feedback to the academic partners on the use of their codes and the added value of the new numerical models developed in WP9 and WP10.
