Healthcare-associated infections (HAI) affect millions of people around the globe. While the most common cause of HAI is direct contact with the source, airborne bacteria may also play a role in patient infections. To prevent airborne infection and make hospital clean rooms safer, it’s important to design efficient ventilation systems. As an added benefit, efficient ventilation designs also lead to lower energy-related costs. The first step to a better design is CFD modeling.

At the COMSOL Conference 2015 Boston, Jeff Crompton from AltaSim Technologies — a COMSOL Certified Consultant — spoke about building, sharing, and deploying apps and what this means for the future of simulation. The team at AltaSim develops apps for a variety of purposes, from analyzing power electronics to additive manufacturing technologies. While some apps are deployed for commercial use, others are customized to meet the specific needs of companies. See how AltaSim is making simulation more accessible with apps.

Doctors can more effectively treat skin cancer when skin tumors are detected early. While visual examinations are typically used to identify such tumors, noninvasive tools like dielectric probes offer another approach. With COMSOL Multiphysics, we analyze the functionality and safety of a dielectric probe used for skin cancer diagnosis.

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.

Polymerase chain reaction tests have many applications within medical and biological research. In the past, these tests have been performed within a laboratory setting due to their high power requirements and the slow speed at which results are delivered. Researchers at the University of California, Berkeley have developed a new LED-based polymerase chain reaction system that, with its simplicity and speed, could be used in point-of-care testing.

3D printing has emerged as a popular manufacturing technique within a number of industries. The growing demand for this method of manufacturing has prompted greater simulation research behind its processes. Engineers at the Manufacturing Technology Centre (MTC) have identified their customers’ interest in a particular additive manufacturing technique known as shaped metal deposition. By building a simulation app, the team is better able to meet the demands of their customers while delivering more efficient and effective simulation results.

Today, we introduce guest blogger Bernd Baumann, who shares insight into optimizing the performance of metal-halide lamps with simulation, with input from his colleague Joerg Schwieger. With the help of COMSOL Multiphysics, we investigated the impact of acoustic resonances and the related acoustic streaming field on the operation of metal-halide discharge lamps. To our surprise, we found that the lamps exhibit behaviors that are similar to a well-known mechanical system — the forced Duffing oscillator with a softening spring.

Heat has a powerful effect on the operation and lifespan of electronic devices. Introducing components like heat sinks within these electronic systems helps maintain cooler temperatures and promotes healthy performance. As we demonstrate with our disk-stack heat sink example, simulation is a powerful tool for analyzing the efficiency of heat sink designs.

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.

Phase change energy storage is an effective approach to conserving thermal energy in a number of applications. An important element in the efficiency of this storage process is the melting rate of the phase-change material, the storage medium. Using the principle of the constructal law as their foundation, a team of researchers sought to advance the performance of these storage systems.
