surface condensation

The formation of water on the exterior surface of cold pipes (or the like) when the temperature of the air falls below its dew point (i.e., the temperature at which the air is fully saturated).

The surface condensation can be controlled by either maintaining the surface temperature higher than the dew point temperature or remaining the partial vapor pressure in the air below the saturation level.
To control the surface condensation with above-mentioned strategies, the surface condensation risk needs to be predicted in advance in relation to heat and moisture transfer in building construction.
Despite their usefulness, these models are not directly applicable to controlling the surface condensation for two reasons.
This section describes 2 separate comparisons of experimental data to the numerical simulation of surface condensation and liquid film formation performed in the analytical CFD software.
A specific mathematical model of surface condensation and evaporation used to perform transient simulations of liquid film formation and removal was presented.
Those results support a discussion on the relevance of each parameter for the surface condensation, wind-driven rain, and drying process.
Exterior Surface Condensation. Exterior surface condensation occurs mostly during the night, when the exterior surface temperature is lower than the dew point temperature, as a result of long-wave radiation exchange between the surface and the atmosphere.
Exterior surface condensation can be analyzed using psychrometry principles.
For the cases shown, VENT-II and CFD modeling agree qualitatively on presence of net surface condensation (continuously "wet" or "dry" conditions), which is consistent with the relining guidelines of the NFGC venting tables.
The first 10 cases, for a double brick chimney (no clay tile liner), show that the most influential parameter with respect to net surface condensation (i.e.
A similar phenomenon (i.e., limited distance of attack) occurs when the fluid is highly conductive, but the fluid is limited to a thin film such as a surface condensation film.
