This example models flow in a microchannel heat exchanger by coupling a Laminar Flow interface in 3D to a Pipe Flow interface. By the use of the Pipe Flow interface to model the flow in the microchannels the problem size is significantly reduced. This model showcases the Pipe Connection ... Mehr lesen
This example reproduces parts of the study of Ref. 1 on the thermal contact resistance at the interface between a heat sink and an electronic package. Eight cooling fins equip the cylindrical heat sink and contact is made at the radial boundaries of the package. The efficiency of the ... Mehr lesen
Geothermisches Heizen ist eine umweltfreundliche und energieeffiziente Methode, um moderne und gut isolierte Häuser mit Wärme zu versorgen. Wärmetauscher, die in ausreichender Tiefe unter dem Haus in den Boden eingelassen werden, nutzen die Wärme aus dem Untergrund, wo die Temperaturen ... Mehr lesen
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). ...

This model is used on "Heat Transfer with Radiation in Participating Media and the Discrete Ordinates Method" to compare quadrature sets used in the method of discrete ordinates. To assess the performance of quadrature sets in complex geometries, results of incident irradiation and ... Mehr lesen
This model studies a part of a shell-and-tube heat exchanger where hot water enters from above. The cooling medium flows through the tubes that, in this model, impose a constant temperature at the walls. Furthermore, the tubes are assumed to be made of stainless steel and the heat flux ...

This tutorial shows how to simulate coupled heat and moisture transport in a wall. The wall is modeled considering an air flow between interior and exterior varying with time. The 1D model is the third benchmark test defined in HAMSTAD-WP2 Modeling for the validation of numerical ... Mehr lesen
This tutorial shows how to simulate coupled heat and moisture transport in a wall made of a load bearing and an insulation layer. Moisture and temperature conditions vary with time on both sides of the wall and rain loading is included. The 1D model is a benchmark test defined in ... Mehr lesen
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 ... Mehr lesen
This model shows how to simulate moisture redistribution inside a wall with capillary active interior insulation. The wall consists of three layers: brick, mortar and insulating material. At the beginning of simulation, there is a sudden change in vapor pressure and temperature at ... Mehr lesen
