Coupling of a zonal air and temperature distribution model with an low pressure environmental control system ducting model

Abstract The Regional Cabin Demonstrator is developed within the Clean Sky 2 project and integrates latest developments in sustainable high-performance cabin interiors for enhanced passenger experience. Within this project, an innovative low pressure environmental control system (ECS) ducting integrated into demonstrator. Together with these hardware demonstration efforts, associated model based development capabilities are strengthened. goal to virtually design aircraft prior its actual integration. Such integration requires heterogeneous submodels interaction overall model. current work presents such a coupling. On one hand, component database 1D simulation developed. By connecting parameterized models, it possible build any desired ECS which drop air outlet flow distributions calculated. This interfaced zonally decomposed indoor environment Modelica-model of showing resulting temperature, stratification airflow. Both models interact on hand because temperature distribution outlets generates boundary condition zonal other part exhaust recirculated thus coupling performed by functional mock-up (FMU) standard allowing couple different through standardized in- outputs while maintaining protection individual partners’ IP. application demonstrated example cruise thermal condition.
