Scaling of mixed convection in aircraft cabins

For the present study of turbulent mixed convection a generic convection cell has been developed. It was designed to work with air as working fluid under high pressure as well as ambient pressure conditions. Based on Particle Image Velocimetry (PIV) and temperature measurements a concept which allows to scale the spatial dimension at turbulent mixed convection by increasing the fluid pressure and adjusting the inflow velocity has been studied. Further analyse the spatial structure of the kinetic energy distribution in mixed convection Proper Orthogonal Decomposition (POD) calculations of the velocity fields have been performed. Results of these investigations are presented
