| Research Abstract |
In this study, we explore the turbulent transport of heat and mass in forced convection flows based on the superposition principle of a passive scalar. For this purpose, we experimentally investigate the effect of thermal and mass boundary conditions on the characteristics of temperature and concentration distributions. A slightly heated and an ethylene dispersed air flow with the same molecular density as air, which are expected with no buoyancy effect, are measured in a wind tunnel. Moreover, we developed measurement techniques to obtain the fluctuating temperature and concentration in turbulent flows with high measurement accuracy.
