Thermal Bridges in Building Construction—3D Structure Between Two Floors

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 ...

Thermal Bridges in Building Construction—3D Iron Bar Through Insulation Layer

This model studies the heat conduction in a thermal bridge made up of an iron bar and an insulation layer that separates a hot internal side from a cold external side. The heat flux between internal and external side and the maximum temperature on the external wall are compared them with published values. This example corresponds to the case 4 described in the European standard EN ISO ...

Thermal Performances of Roller Shutters

During the design of a building, environmental issues have gained considerable influence in the entire project. One of the first concerns is to improve thermal performances. In this process, simulation software are key tools to model thermal losses and performances in the building. The international standard ISO 10077-2:2012 deals with thermal performance of windows, doors and shutters. It ...

Optimizing a Thermal Process

A thermal processing scenario is modeled whereby two heaters raise the temperature of a gas flowing through a channel. The Optimization Module is used to find the heater power to maximize the outflow temperature, while maintaining a constraint on the peak temperature at the heaters themselves.

Thermal Bridges in Building Construction—2D Square Column

This example studies heat transfer in a square column. Cold and hot temperature conditions are applied to the boundaries. Due to the symmetry of the problem, the geometry is simplified to half of the square. The temperature field is compared with the analytic data. This example corresponds to the case 1 described in the European standard EN ISO 10211:2007 for thermal bridges in building ...

Glazing Influence on Thermal Performances of a Window

During the design of a building, environmental issues have gained considerable influence in the entire project. One of the first concerns is to improve thermal performances. In this process, simulation software are key tools to model thermal losses and performances in the building. The international standard ISO 10077-2:2012 deals with thermal performance of windows, doors and shutters. It ...

Buoyancy–driven μPCR for DNA Amplification

Polymerase chain reaction (PCR) is one of the most effective methods in molecular biology, medical diagnostics, and biochemical engineering in amplifying a specific sequence of DNA. There has been a great interest in developing portable PCR-based lab-on-a-chip systems for point-of-care applications and one strategy that seems very promising is natural convection-based PCR. This model studies ...

Shell Conduction

This model simulates a static analysis of heat conduction in a thin conductive shell. This is a benchmark model where the result is compared with a NAFEMS benchmark solution.
