Pitting corrosion is a type of localized corrosion by which local cavities, pits, are formed on an initially smooth metal surface. A pit may be initialized by surface defects, such as an inhomogeneities in composition or shape, or mechanical abuse resulting in a small scratch or dent. ... En savoir plus
Many applications involve simulating the electromagnetic behavior of relatively thin material in voluminous domains. To save computer memory and processing time, the thin materials can be treated differently by resolving them with 3D meshes. Here, the modeling domain is a box filled ... En savoir plus
In this example, a heat-conduction problem with phase change in a porous material is solved, and the results are compared with the analytical solution, also known as the Lunardini solution. This is the first benchmark case from the InterFrost project, which was initiated to compare ... En savoir plus
Biotechnology is a rapidly growing area in the pharmaceutical sciences. One example of a clinical application is gene therapy, where it is possible to produce proteins in vivo, using the body’s own mechanisms for protein production. Major issues in gene delivery involve the transport of ... En savoir plus
This tutorial uses a 2D model of an acoustically driven microfluidic pump. The acoustic microfluidic pump is driven by acoustic streaming originating from sharp edges in the microfluidic channel. It drives a flow around a closed microfluidic channel loop. The acoustic field is modeled ... 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
At the macroscopic level, systems usually mix fluids using mechanical actuators or turbulent 3D flow. At the microscale level, however, neither of these approaches is practical or even possible. This model demonstrates the mixing of fluids using laminar-layered flow in a MEMS mixer. This ... En savoir plus
This example was originally formulated by Albert Witarsa under Professor Bruce Finlayson’s supervision at the University of Washington in Seattle. It was part of a graduate course in which the assignment consisted of evaluating the potential of patents in the field of microfluidics ... En savoir plus
The development of mixers does often not only have to account for effectiveness, but also other factors must be involved, such as cost and complexity for manufacturing. The three models study a laminar static micro mixer with two parallel sets of split-reshape-recombine mixing elements. ... En savoir plus
This example describes an array of heating tubes submerged in a vessel with fluid flow entering at the bottom. This is a multiphysics model because it involves fluid dynamics coupled with heat transfer. The pressure and the velocity field are the solution of the Navier-Stokes equations, ... En savoir plus
