Fraunhofer ISE Simulates a Solar Heating and Cooling System

Brianne Costa | October 27, 2015

Keeping buildings cool in the summer and warm in the winter is a major drain on energy resources. In search of a more cost-effective and energy-efficient way to heat and cool buildings, researchers at Fraunhofer ISE continuously work to develop adsorption-based systems that run on solar energy, natural gas, and industrial waste. Using COMSOL Multiphysics® simulation software, the team investigates the adsorption process, heat exchanger design, and numerous other systems that affect their innovative developments in adsorption technology.

Wireless power transfer involves the transfer of power between a transmitting and a receiving unit and is used to wirelessly charge electronics like mobile phones and electric cars. While wireless power transfer offers many benefits, there are some challenges that this technology encounters. This is where simulation comes in handy. For instance, some WPT technologies must be oriented in a certain way to ensure proper performance. Today, we’ll analyze the impact of orientation on the functionality of two WPT antennas.

When flowing through a constricted area of a pipe, a fluid’s velocity increases and its static pressure decreases. This principle is known as the Venturi effect. Today, we will take a closer look at this effect, including some of its applications.

As a technical support engineer, one of the most common technical questions I receive is: “How can I compute the mass conservation of a fluid flow simulation or the energy balance of a conjugate heat transfer simulation?” This is often requested to investigate and ensure a simulation’s accuracy. Here, I will demonstrate how to perform these calculations in COMSOL Multiphysics and introduce some of the predefined variables available for postprocessing the energy rate terms of the energy balance equation.

Arteries are designed to carry blood containing oxygen and nutrients from the heart to other areas of the body. Studying this biological soft tissue from a mechanical standpoint requires a reliable model that can fully describe the arteries’ anisotropic nonlinear response. Our tutorial of arterial wall mechanics illustrates such a design.

Clinton Davisson is an American physicist best known for his discovery of electron diffraction through the Davisson-Germer experiment. His findings brought about important developments in the field of quantum mechanics. On this day, which would have been his birthday, we celebrate Davisson’s storied history and many contributions to science.

The shortest route between two points isn’t necessarily a straight line. If by shortest route, we mean the route that takes the least amount of time to travel from point A to point B, and the two points are at different elevations, then due to gravity, the shortest route is the brachistochrone curve. In this blog post, we demonstrate how to use built-in mathematical expressions and the Optimization Module in COMSOL Multiphysics to solve for the brachistochrone curve.

MEMS resonators are microelectromechanical systems primarily used as sensor elements, filters, and frequency elements. Two common actuation methods for MEMS resonators are piezoelectric actuation and electrostatic actuation. In this blog post, we will discuss the modeling of electrostatically actuated MEMS resonators. When modeling such resonators, you will often come across terms such as equilibrium point, pull-in, pull-in voltage, and time harmonic response of a biased resonator. We will explain these phenomena using a simple representation of an actuator.
