STUDY ON THE EFFECT OF CURTAINS ON DEW CONDENSATION ON WINDOWS: The Lewis number during dew condensation in laboratory experiment

The amount of condensation water on the window glass surface is determined by multiplying the window glass area, the absolute humidity difference, and the moisture transfer coefficient. The moisture transfer coefficient is determined from the convective heat transfer coefficient and the Lewis number...

Zusammenfassung:The amount of condensation water on the window glass surface is determined by multiplying the window glass area, the absolute humidity difference, and the moisture transfer coefficient. The moisture transfer coefficient is determined from the convective heat transfer coefficient and the Lewis number. Therefore, it is essential to identify the Lewis number in order to calculate the condensation water content. In this study, the Lewis number was calculated from the experimental results of temperature, wind velocity, and condensation water weight, and it was confirmed that the Lewis number for window condensation is 1.7 to 2.1 with curtains.
