Condensation Risk in a Wood-Frame Wall

This 2D stationary model computes heat and moisture transport in a wall composed of different hygroscopic materials. A comparison with the Glaser method is given for the temperature and relative humidity solutions. The effect of the use of a vapor barrier is also investigated. Saiba Mais

Concentric Tube Heat Exchanger

Finding the right dimensions for a heat exchanger is imperative to ensure its effectiveness. Other properties must also be considered in order to design a heat exchanger that is both of the right size and provides heated or cooled fluid of the right temperature. The Concentric Tube Heat ...

Nonisothermal Turbulent Flow over a Flat Plate

This verification model of nonisothermal turbulent flow over a flat plate compares the heat transfer coefficient obtained from simulation with theoretical values based on Nusselt number correlation functions that can be found in the literature. Saiba Mais

Isothermal Box

This example solves the heat transfer in an isothermal box aimed at transporting refrigerated articles such as medical materials for 24 hours. In this case, the box not only has to keep the content cold in a long period of time, but also has to respect a storage temperature restriction. ... Saiba Mais

Heat and Moisture Transport in a Semi-Infinite Wall

The model is defined as a benchmark case in norm 15026:2007 annex A. The purpose of the model is to calculate the temperature and moisture profiles at different times after a change in the external conditions (temperature and relative humidity) inside a wall material (kind of concrete). ...

Dynamic Wall Heat Exchanger

The heat exchanger in this tutorial model contains a dynamic wall with an oscillating wave shape. The deformation induces mixing in the fluid and reduces the formation of thermal boundary layers. Hence, it increases heat transfer between the walls and the fluid. In addition, the wave ... Saiba Mais

Equivalent Properties of Periodic Microstructures

Periodic microstructures are frequently found in composite materials, such as carbon fibers and honeycomb structures. They can be represented by a unit cell repeated along three directions of propagation. To reduce computational costs, simulations may replace all of the microscopic ... Saiba Mais

Rapid Thermal Annealing

In the semiconductor industry, rapid thermal annealing (RTA) is a semiconductor process step used for the activation of dopants and the interfacial reaction of metal contacts. In principle, the operation involves rapid heating of a wafer from ambient to approximately 1000–1500 K. As soon ... Saiba Mais

Modeling a Conical Dielectric Probe for Skin Cancer Diagnosis

The response of a millimeter wave with frequencies of 35 GHz and 95 GHz is known to be very sensitive to water content. This model utilizes a low-power 35 GHz Ka-band millimeter wave and its reflectivity to moisture for noninvasive cancer diagnosis. Since skin tumors contain more ... Saiba Mais

Silica Glass Block Coated with a Copper Layer

In this time-dependent model, a silica block of glass, coated with a thin copper layer is subjected to a heat flux. Copper is a highly conductive material, while the silica glass is of poor thermal conductivity, which sets up an highly-varied temperature differential. The model must ... Saiba Mais
