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
A journal bearing is composed of an outer cylinder (bearing) wrapped around an inner rotating journal (shaft), with a lubricant separating the two. Under certain operating conditions, cavitation can occur between the bearing and the journal, leading to component damage and failure. ... 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
This example demonstrates how to import and repair a surface mesh from an STL file, and to create a mesh to simulate nasal spray application inside the human upper airways. It further demonstrates how to combine the repaired mesh with the geometry of a nasal spray, then to remesh and ... En savoir plus
Nucleate boiling occurs when a liquid is heated by a source hotter than the saturated fluid temperature but with a heat flux below the critical heat flux. In this regime, high heat flux are possible due to the evaporation of the liquid. This model aims to demonstrate the calculation of ... En savoir plus
This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic slider bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case. En savoir plus
The process of filling a water balloon is a vivid example for the interaction of fluid pressure and a nonlinear structural material. This model demonstrates how straightforward a FSI simulation model is set up in COMSOL. En savoir plus
This tutorial model can be used to learn how to calculate mass and energy balances. Get a detailed demonstration in this blog post: How to Calculate Mass Conservation and Energy Balance En savoir plus
The model has its emphasis on heat transport in a very small heat exchanger that is commonly used in the field of microelectromechanical systems (MEMS). In this case, it might be a reactive processes that needs heating. The heat exchanger itself is constructed by stacking several ... En savoir plus
