1D Plane Slider bearing

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.

Bending Pipe

This model studies the fluid flow through a bending pipe in 3D for the Reynolds number 300 000. Because of the high Reynolds number, the k-epsilon and the k-omega turbulence models are used. Calculations with and without corner smoothing are performed. The results are compared with experimental data.

Fully-coupled Physics with Joule Heating, CFD and Chemical Reactions

In this example, a fluid carrying several chemical components is pumped into a detector compartment. A wire in the center of the detector is heated through Joule heating, which is supposed to detect changes in density through convective cooling. However, the higher temperature around the wire causes the ignition of exothermic chemical reactions, which in turn increase the temperature even more. ...

Optimizing a Thermal Process

A thermal processing scenario is modeled whereby two heaters raise the temperature of a gas flowing through a channel. The Optimization Module is used to find the heater power to maximize the outflow temperature, while maintaining a constraint on the peak temperature at the heaters themselves.

Buoyancy–driven μPCR for DNA Amplification

Polymerase chain reaction (PCR) is one of the most effective methods in molecular biology, medical diagnostics, and biochemical engineering in amplifying a specific sequence of DNA. There has been a great interest in developing portable PCR-based lab-on-a-chip systems for point-of-care applications and one strategy that seems very promising is natural convection-based PCR. This model studies ...
