The process of humid air condensing on a cooler surface has a lot of implications in our daily lives. Formation of dew, fog, mist and other natural phenomena occurs due to condensation of water vapor. This causes dampness and blocks vision on windowpanes in a house, the windscreen of a car and other areas. Furthermore, it causes erosion of engineering equipment as the condensate formed on the walls is often cause for concern. It affects the intended performance of engineering systems, making it imperative to consider it during the design phase. Quantification of wall condensation helps designers to implement techniques to mitigate this risk. Several Computational Fluid Dynamics (CFD)-based techniques are available that can predict the condensate formation at the walls resulting from lower temperatures.

Our latest whitepaper describes a CFD simulation that predicts wall film formation inside an electronic control box. The simulation is preformed using the Eulerian Wall Film (EWF) model, which is available in the commercial CFD code ANSYS FLUENT.
