The objectives of this activity are:- To assess the reliability of European mathematical codes used to size the thickness of ablative TPS (Thermal Protection System) on entry heat shields;- To refine and possibly reduce the related uncertainties;- To identify relevant areas to improve the codes.In order to reach these objectives, the following steps shall be performed within the activity, as further detailed in chapter 2:- Establish a booklet with a set of numerical ablation test cases based on material characterisation and plasma test results of the ZURAM material (task 5)- Where necessary the available data shall be complemented by relevant additional material characterisation (task 2)- Dedicated plasma tests shall be defined and performed (task 3)- Coupling of a response code for charring ablators with a code for equilibrium chemistry calculations (task 5)- Model and run the defined numerical testcases with at least three of the mathematical codes available in Europe for ablative TPS sizing (task 6)- Compare the results withthe available plasma test data, assess the code/model performance and identify the weaknesses of the used codes (task 6)- Derive relevant model uncertainties based on the test cases and extrapolate these uncertainties to relevant entry analysis (task 7)- Identifyrelevant code improvements and recommended code delta-development (task 7).
