Description :
Over the last twenty years a thermal response code for charring
ablators has been developed at LMS Samtech, called SAMCEF
Amaryllis. This code is being used in the European aerospace industry
(Astrium, ESA/ESTEC, MBDA,…) for the thermal design of heat
shields. Today, a functionality that is missing is the chemistry
modeling necessary in order to calculate the ablation speed (a
boundary condition in Amaryllis) and gas enthalpies. At the Von
Karman Institute (VKI) a chemistry library has been developed
(Mutation++) that can calculate (among other things) equilibrium
chemistry states (enthalpy, ablation rate) for multi-species gases.
Within this project both codes will be put together in order to solve the
ablation problem.
The project will proceed in several steps:
 First the student will familiarize him/herself with both codes
(Amaryllis and Mutation++), using the example from the Code
comparison test-case series (initiated by NASA).
 Secondly all the chemistry data for this test-case will be regenerated and compared with the chemistry data used today.
 Then Mutation++ and Amaryllis will be coupled together,
using the existing user routines in Amaryllis, and compare the
results (thermal response) between the present day approach
(using pre-generated input tables) and the new approach where
we calculate the properties on the fly.
 Finally the coupled solver will be applied to a 3D example,
which can be either the iso-q specimen from the code
comparison working group, or the re-entry cube-sat QARMAN
(VKI).
