Magnetic Cooling Technology in Refrigeration
While the concept has been around for quite some time, magnetic cooling technology has only recently emerged as a potential method of refrigeration within households. Here, we take a closer look at how this new technology offers a greener approach to preserving foods.
Combining Parallel Slices to Create an Animation
Creating animations is an effective way to present and visualize simulation results. In COMSOL Multiphysics, this is fairly straightforward using the Player node for time-dependent or parameter sweep study types. But, can we animate how the solution changes along a direction in a 3D steady-state model? The answer is yes. Here, we will learn how to combine parallel slices to create an animation for a 3D steady-state example model, using a three-step process.
Accurate Hematology Analysis Using Hydrofocusing
Hematology analysis is an important step in medical diagnoses, often determining the treatment that a patient will receive. With a patient’s life on the line, it is vital that these analyses are accurate to the highest degree possible. Researchers at HORIBA Medical, a worldwide supplier of medical diagnostic equipment, turned to simulation to develop new methods for optimizing the accuracy of their hematology analysis devices. The resulting technique is currently used in some of their best-selling equipment.
Selective Laser Sintering for Prototype Production
In a recent blog post, we discussed the growth in 3D metal printing and its impact on manufacturing. Today, we shift our focus from the industry as a whole to a particular technique that has been instrumental in the production of metal prototypes, as well as plastic, ceramic, and glass materials — even coffee. Selective laser sintering has taken the world of 3D printing by storm.
Modeling a Coil Heat Exchanger
Coil heat exchangers are simple and easy to manufacture. Here, we consider an axially wound coil of copper carrying hot water that heats air inside of a circular duct. Since the geometry is almost invariant about the centerline, the model is solved in the 2D axisymmetric plane. Additional expressions are added to compute the temperature drop between turns of the coil, which greatly simplifies the modeling.
Reducing Vibrations with Viscoelastic Structural Dampers
In the design of many structures, a particular area of concern is exposure to seismic and wind-induced vibrations. Viscoelastic structural dampers have been implemented into structural layouts as a means to limit the strain and decrease the risk of failure in building components due to such excitations.
The Hygroscopic Swelling Effect
There have been many studies of how specific materials are affected by hygroscopic swelling. Let’s explore what hygroscopic swelling is and the effect it may have on engineering designs.
How to Obtain Oil Cost-Effectively with Multilateral Wells
Safe and cost-effective drilling is a major issue in the oil and gas industry. In addition to the common prospecting risk, the borehole itself provides uncertainties that are not desired, but unavoidable. Today, we would like to show how numerical simulations can help here. The goal is to predict the stability of an open-hole multilateral well for deciding if the well will need expensive mechanical stabilization — or not.
