Computational Fluid Dynamics (CFD) for Condensation Risk Assessment of Glazing Systems
Abstract
Air flow and radiation exchange has a significant impact on the surface temperatures of glazing systems. Assessment of surface temperatures are essential in evaluating condensation risk of glazing systems. Common approaches to assessing condensation utilize steady state simulations and standardized assumptions that do account for dynamic conditions. Consequently, teams often want to turn to computational fluid dynamics (CFD) to answer complex questions related to the impact of specific HVAC designs and obstructions that affect air flow, such as structural columns. However, will CFD lead to better insights and is the extra effort worth it?
This paper presents an investigation into the use of CFD for condensation risk assessment of glazing systems with a full room model and shows an example where CFD might be worth it.
