This example studies the stationary state of free convection in a cavity filled with air and bounded by two vertical plates. To generate the buoyancy flow, the plates are heated at different temperatures, set in a range to keep the flow laminar. En savoir plus
This app demonstrates the following: A model using symmetry while the results are visualized in full 3D Provides info if the results are above or below certain critical values Selecting predefined or user-defined materials Error control of geometry parameters using methods and ... 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 tutorial shows how to couple three physics interfaces to model evaporative cooling. The effects that need to be taken into account are heat transfer, transport of water vapor, and fluid flow. The Wet Surface feature is used to implement the source term for the water vapor and to ... En savoir plus
Plate reactors running under continuous conditions have emerged as candidates to replace batch reactors, primarily in fine chemicals and pharmaceuticals production. One of the advantages of the plate reactor design is that it allows for efficient temperature control of the reacting ... En savoir plus
Thermal management has become a critical aspect of today’s electronic systems, which often include many high-performance circuits that dissipate large amounts of heat. Many of these components require efficient cooling to prevent overheating. Some of these components, such as processors, ... En savoir plus
This model describes the three heat transfer modes: conduction, convection, and radiation, combined with nonisothermal flow in a realistic geometry representing a light bulb and the surrounding air. The LED chips dissipate heat. The model computes the equilibrium temperature induced by ... En savoir plus
This tutorial models the intercoupled electrochemical reactions, charge and species transport as well as heat transfer in a polymer electrolyte membrane (PEM) fuel cell. For the gas flow fields, straight channels are used on the hydrogen anode side, whereas a mesh structure is used on ... En savoir plus
This example shows how to set up a glacier flow model in principle, containing several important aspects of glacier modeling: The creation of the 2D geometry, the modeling of non-Newtonian flow, and the implementation of basal sliding. In this example, two different glacier types, a cold ... En savoir plus
