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 ... En savoir plus
In friction stir welding, a rotating tool moves along the weld joint and melts the aluminum through the generation of friction heat. The tool’s rotation stirs the melted aluminum such that the two plates are joined. In this model, two aluminum plates are joined by generating friction ... En savoir plus
This classical verification model solves the steady state temperature distribution in a plan disk heated by a localized heat source at its center. It shows and compare different ways to define a heat source localized on a small domain by representing it either as a geometrical point or a ... En savoir plus
This model demonstrates how to vary the inlet temperature in a superheated steam drying process so as to minimize the time, while constraining both the energy consumption and the final moisture content. En savoir plus
This tutorial model demonstrates the use of the Moisture Flow coupling node to account for the Stefan flow in moist air, over an evaporation surface. The effects on the velocity field and vapor concentration are presented with different ambient temperature conditions. En savoir plus
This model of a two-story house can be used to examine a contaminant leak and the subsequent contaminant dispersion that occurs due to convection and diffusion. Airflow and recirculation within the home are dependent on vent placement, and flow velocity may also vary at each vent. ... En savoir plus
This example studies the stationary state of free convection in a cavity filled with water and bounded by two vertical plates. To generate the buoyancy flow, the plates are heated at different temperatures, bringing the regime close to the transition between laminar and turbulent. To ... En savoir plus
This example uses the thermal expansion of a laminated composite shell model to demonstrate the use of the feature Thermal Contact, Interface, applied on interfaces between layers in a laminated composite shell. The first study is computed neglecting this additional thermal resistance in ... En savoir plus
This tutorial presents the averaging models available within the Heat Transfer in Porous Media interface, used to compute the effective thermal conductivity, when the local thermal equilibrium assumption is made. The models are compared for porosities ranging from 0 to 1, and for a ... En savoir plus
This example is about the modeling of the fiber drawing process. Thermal fiber drawing is a process in which a comparatively thicker structure is heated and drawn into extended lengths of microstructured fiber. This process is done by passing them through the furnace and pulling them ... En savoir plus
