Abstract
Temperature and humidity measurements are performed in mixed convective moist-air duct flows for the Reynolds numbers Re= 2000, 4000 and 6000 with condensation at a cooled wall in a vertical rectangular duct. The width-to-height ratio is 10.66:1. A comparison of experimental results obtained with passive insulation on the wall opposite to the cooled wall for Re=2000 with results of direct numerical simulations performed under adiabatic boundary conditions reveals large differences. The latter are significantly reduced by realising an active insulation with isothermal boundary conditions. Using this set-up, it is shown that the heat and mass transfer in terms of the Nusselt and Sherwood number increase with the Reynolds number.
