Behavior of Power Law Fluids in a Mixer

This model shows how to use simulations to predict power numbers with Power Law fluids in a mixer. It simulates the behavior of flow in a flat bottom tank with a single four-blade pitched impeller. The flow was modeled as laminar and the frozen rotor approach was used to solve the discrete governing equations in one quarter of a baffled tank. The calculated power numbers were compared with ...

Electrodeposition of a Microconnector Bump with Deforming Geometry in 3D

This model simulates the shape evolution of a microconnector bump over time as copper deposits on an electrode surface. Transport of cupric ions in the electrolyte occurs by convection and diffusion. The electrode kinetics are described by a concentration dependent Butler-Volmer expression. The model is an extension to 3D of the Electrodeposition of a Microconnector Bump in 2D example.

Noise Radiation by a Compound Gear Train

This example illustrates the modeling of noise radiation from the housing of a gear train. First, a multibody analysis is performed in the time domain to compute the housing vibrations at the specified driver shaft speed. Then, an acoustic analysis is performed at a selected frequency to compute the sound pressure levels in the near, far, and exterior fields using the housing normal ...

Electrical Heating in a Busbar

This tutorial model of the Joule heating effect in a busbar demonstrates how to synchronize an assembly between Solid Edge and COMSOL, how to modify the geometry from COMSOL, and how to run a geometric parametric sweep.

Slip Flow Benchmark

This model is a benchmark model for the Slip Flow interface. It is based on both analytic and numeric calculations. Air at atmospheric pressure flows through a conducting micro-channel connecting two reservoirs maintained at different temperatures. A flow between the two reservoirs develops as a result of thermal creep along the channel wall, which in turn produces a pressure gradient. At steady ...

Simulation of an Electromagnetic Sounding Method for Oil Prospecting

The marine controlled source electromagnetics method (CSEM) for oil prospecting has emerged as a promising technique during recent years. This model demonstrates one variant of it. It uses a mobile horizontal 1 Hz electric dipole antenna that is towed 150 m above the sea floor. An array of sea floor receivers measure the electric field at various distances away from the antenna. When measuring ...

Parameterized Window Preset Model

During the design of a building, environmental issues have gained considerable influence in the entire project. One of the first concerns is to improve thermal performances. In this process, simulation software are key tools to model thermal losses and performances in the building. The international standard ISO 10077-2:2012 deals with thermal performance of windows, doors and shutters. It ...

Doppler Shift

We have all noticed the Doppler effect when an ambulance passes by with its sirens blaring. The siren’s pitch suddenly drops the moment the ambulance starts moving away from you. Another effect you can notice is how the siren’s sound is very loud when nearby, but as soon as the ambulance has passed the sound becomes much quieter. This model simulates the acoustic Doppler effect by placing ...

Semibatch Polymerization

As reactant monomer converts into polymer chains, the density of the reacting mixture often changes notably. In this example you will look at how this effect impacts the total production of polymer in a process. The liquid phase polymerization takes place in a semibatch reactor, where two operating conditions are compared. In the first scenario, the feed of monomer to the reactor is turned off ...

Kirsch Infinite Plate Problem

This model describes a static stress analysis to obtain the stress distribution in the vicinity of a small hole in an infinite plate. The model is a classic benchmark and is described in Mechanics of Material, by D. Roylance. The stress level is then compared with the theoretical values.
