In this example, a heat transfer model of a fiber composite's unit cell is analyzed with the Cell Periodicity feature. The homogenized thermal conductivity, density and heat capacity of a composite material are computed based on the individual properties of fiber and matrix. A comparison ... En savoir plus
Computing molecular flows in arbitrary geometries produces complex integral equations that are very difficult to compute analytically. Analytic solutions are, therefore, only available for simple geometries. One of the earliest problems solved was that of gas flow through tubes of ... En savoir plus
The purpose of this model is to introduce the Semitransparent Surface Feature from the Radiation in Participating Media Interface. It is a variation of the Radiative Cooling of a Glass Plate model with the DOM method. In this version a semitransparent surface is defined on external ... En savoir plus
This tutorial demonstrates how to simulate coupled heat and moisture transport in an insulated roof structure composed of a load-bearing layer and an insulation layer. The thermal insulation faces the interior, while a moisture barrier is placed on the exterior side. The load-bearing ... En savoir plus
This model performs a transient analysis of the temperature through a house wall. The wall is formed of different layers corresponding to the structure, insulation and plaster. On the exterior and the interior, the wall is exposed to thermal radiation and convective cooling. The results ... En savoir plus
This tutorial demonstrates how to use the temperature and relative humidity computed from a heat and moisture transport simulation of an insulated roof as inputs for a mold prediction model. The VTT model for mold growth and decline prediction calculates a mold index M by solving an ... En savoir plus
This model simulates a cylindrical furnace with isotropic scattering. It validates the use of the Discrete Ordinates Method for 2D axisymmetric cases, comparing the results with the highly accurate Monte Carlo method. The setup and reference Monte Carlo values are given in: R .P. Gupta, ... En savoir plus
This model simulates the flow through a uniform inclined screen using the Screen feature in Single-Phase Flow physics and compares the results with an analytic solution. En savoir plus
The Pipe Flow interface allows you to simulate non-Newtonian fluids flowing in pipes. This example models a coal slurry being transported in a pipe system where the pipe diameter changes in different sections. The slurry behaves as a non-Newtonian fluid described by the power law model. ... En savoir plus
Turbulent flow, SSG-LRR interface is employed to investigate turbulent flow in a straight semicircular duct. The resulting flow pattern is characterized by slow secondary motions in the plane normal to the duct axis. The order of magnitude of velocity of those motions is 1% of the ... En savoir plus
