Thermal Bridges in Building Construction - 3D Structure Between Two Floors
Application ID: 12573
This model studies the heat conduction in a building structure separating two floors from the external environment. Four materials with distinct thermal conductivities k compose the structure. The exterior and interior boundaries are facing environments respectively at 0°C and 20°C. The lowest temperatures on internal surfaces and the heat fluxes through each surface is compared with published data.
This example corresponds to the case 3 described in the European standard EN ISO 10211:2007 for thermal bridges in building constructions.
COMSOL Multiphysics passes successfully all the test cases described by the standard and is hence classified as a three-dimensional steady-state high precision method.
This model example illustrates applications of this type that would nominally be built using the following products:伝熱モジュール
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:
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 製品仕様一覧 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.
