This model shows how to compute an array of borehole heat exchangers (BHEs) for shallow geothermal energy production. The BHEs are simplified as line heat sinks with a uniform heat extraction rate. The array is embedded into a layered subsurface model with groundwater flow in one of the ... En savoir plus
A 3D model of an acoustic trap in a glass capillary actuated by a piezoelectric transducer. The system is actuated by an oscillating electric potential across the piezoelectric transducer inducing mechanical vibrations in the solid and an acoustic pressure field in the fluid. The heat ...

This model computes the transmission probability through an RF coupler using both the angular coefficient method available in the Free Molecular Flow interface and a Monte Carlo method using the Mathematical Particle Tracing interface. The computed transmission probability determined by ... En savoir plus
In the semiconductor manufacturing process, photoresist coating is an important process and the thickness of the photoresist layer needs to be precisely controlled. Usually, the photoresist layer is thinned by spin coating. The specific principle is to use centrifugal force to throw ... En savoir plus
This model simulates the separation and mixing of a suspension with light and heavy particles. Initially the distribution of both particle populations is homogeneous throughout the fluid. Before the impeller starts rotating, the fluid and the two particle populations tend to separate ... En savoir plus
This model represents a stove in a living room. A radiation study is performed with the Surface-to-Surface Radiation physics interface. It shows the intensity of the stove radiation received on different surfaces of the room. En savoir plus
A 2D model of a steel bar is used to simulate oil quenching from an austenitic state. Both diffusive and displacive phase transformations are used, and the phase composition is computed in the radial direction of the bar. En savoir plus
This tutorial model illustrates how to calculate the pressure drop and initial flow rate in a pipe system connected to water tank. The Pipe Flow interface contains ready to use friction models accounting for the surface roughness of pipes as well as pressure losses in bends and valves. En savoir plus
Flow over a cavity and the tonal noise generated is a typical flow noise source in piping systems that have valves and other cavities. This tutorial model represents a simple case of cavity flow noise in a ducted system. The model is set up based on an example from Lafon et al. The ... En savoir plus
This model simulates an H-shaped micro-cell designed for diffusion-controlled separation. The cell puts two different laminar streams in contact for a controlled period of time. The contact surface is well-defined and, by controlling the flow rate, it is possible to control the amount of ... En savoir plus
