TheReSE: SysML extension for thermal modeling

During the conceptual design phase, System Architects perform fast pre-validation of alternative architectures of the system to be designed. In order to provide them with a means to achieve this task, a SysML extension called TheReSE is proposed. It aims at modeling thermal effects on components with simplified geometry, by covering radiation, conduction, and convection heat transfers. It also ensures traceability between requirements and simulation results. In order to assess the relevance of this extension, this approach has been applied to an aircraft air conditioning case study.
