In 1898, Carl Miele and Reinhard Zinkann founded the Miele company. Since then, it has grown into one of the world’s foremost producers of household appliances, including washing machines and cooking devices for both domestic and professional use. Miele has created a joint research laboratory, mieletec, with the University of Applied Sciences in Bielefeld, Germany. There, the foundations are being laid for the next generation of resource and energy efficient household appliances. This October, you have the chance to hear […]

A contact switch is used to regulate whether or not an electrical current is passing from a power source and into an electrical device. These switches are found in many types of equipment and they are used to control, for example, the power output from a wall socket into a device when it is plugged in; the currents passing across the circuit board of a computer; or the electricity powering a light bulb when the switch is flipped on. Because of their […]

Julie Slaughter and her team at ETREMA Products are in the enviable position as the sole U.S. provider of the smart material Terfenol-D, and developer of products based on this material. Terfenol-D is said to produce giant magnetostriction that boasts strains 100 times higher than traditional magnetostrictive materials, such as iron. Just imagine the possibilities of applications harnessing this amazing material property. If you’re attending the COMSOL Conference in Boston this October, you will hear ETREMA talk about transducer design […]

The COMSOL Conference makes three major stops across the globe annually in the United States, Europe, and India. The exact locations within these geographical areas are not chosen at random; they are top-traveled cities with lots to see and do while you’re there. While the main focus of the event is (of course) to bring together multiphysics enthusiasts, we want to help make the most out of your visit as a whole. Here is your guide to the three major […]

There are many different forces that can induce flow in fluids, such as kinetic energy, pressure gradients, concentration gradients, and many more. In natural systems, one effect that can initiate fluid flow in a still fluid is a change in density. This density change will result in a change in the fluid’s buoyancy, thus inciting flow as the denser fluid sinks and the less dense, buoyant, fluid rises. You’re probably most familiar with these changes in density occurring due to […]

Research on fatigue started in the 19th century, initiated following failing railroad axles that caused train accidents. In a rotating axle, stress varies from tension to compression and back to tension in one revolution. The load history is simple because it is uniaxial and proportional. Fatigue can then be evaluated with the S-N curve, also known as the Wöhler curve, which relates stress amplitude to a component’s life. In many applications we deal with multiaxiality and non-proportional loading. In this […]

The way the sound is shaped as it passes through the pipe of an organ is the result of a carefully calculated and intricate pipe design. Browsing through the Model Gallery, I came across a model of an organ pipe, and it happens to be a great acoustics tutorial for using the Pipe Acoustics, Frequency Domain interface in COMSOL Multiphysics. Let’s talk organ pipe design, and walk through how we can model it with multiphysics software.

Underground medium voltage cables are often used to deliver electrical power from a transmission system and into the home of consumers. In the United Kingdom, these cables carry hundreds of amps at voltages between 11 and 33 kV, a typical voltage of electrical transmission cables around the world. Analyzing the stresses that these cables are exposed to over their lifetime is important for ensuring both consumer safety and energy efficiency. Researchers from the Glasgow Caledonian University in Scotland used COMSOL […]

Our day-to-day lives are dependent on the safety of technical systems and processes. We blindly trust that reactor vessels withstand the test of time, that the train or ship we’re on does not break down. These metal structures, in turn, rely on accurate welding processes. Here’s where BAM Federal Institute for Materials Research and Testing comes into the picture. BAM researchers have been working on improving upon the high-power laser beam welding process in order to promote safer and more […]
