HAMSTAD Benchmark 1: Heat and Moisture Transport in an Insulated Roof
Application ID: 75601
This tutorial shows how to simulate coupled heat and moisture transport in an insulated roof structure, made of a load bearing and an insulation layer. The thermal insulation is facing the interior and there is a moisture barrier facing the exterior. The load bearing is capillary active while the insulation layer is capillary non-active, which induces high relative humidity levels at the contact surface between the two materials, resulting in internal condensation. The 1D model is the first benchmark defined in HAMSTAD-WP2 Modeling for the validation of numerical simulations for coupled heat and moisture transport in building materials. See 75741, Heat and Moisture Transport with Mold Growth Prediction for a mold growth prediction study with the VTT model based on the numerical results of temperature and relative humidity of this model.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- either the Heat Transfer Module, or Porous Media Flow Module
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
