DEVELOPMENT OF A CFD MODEL AND METHODOLOGY FOR THE INTERNAL FLOW SIMULATION IN A HYDROGEN-POWERED UAV

A. Porcarelli, KTH - Royal Institute of Technology, Sweden

The onboard carrying of a hydrogen fuel cell leads to unexplored internal flow characteristics, including the introduction of water vapour. Given the strict environmental operational requirements of PEM fuel cells, a Runge-Kutta-based solver is developed and tested to effectively assess the evolution of the UAV internal bay flow temperature and humidity fields.
