This is now easier to account for using the Wet surface and Moist surface boundary conditions. Not only do these mechanisms influence the material balance between vapor and water, but they also greatly influence the energy balance due to latent heat. Water condensation and evaporation on surfaces may also play a significant role in applications simulating moisture transport in air. In this case, moisture and heat transport in air are automatically coupled in domains where building materials are defined. The two interfaces can be coupled using the Heat and Moisture multiphysics feature. This feature handles moisture transport by convection and diffusion in air as well as turbulent mixing caused by eddy diffusivity when you need to account for turbulent moisture convection. A Moist Air feature is available in the Heat Transfer in Moist Air and Moisture Transport interfaces. Heat and Moisture TransportĬOMSOL Multiphysics ® version 5.3 includes several features to further extend the modeling of heat and moisture transport in air. Learn about these heat transfer features and more below.

For users of the Heat Transfer Module, COMSOL Multiphysics ® version 5.3 includes new functionality to model heat and moisture transport in air, a new solver for modeling heat transfer in the frequency domain, and heat sink geometry parts to more easily create certain geometries.
