App: Ensuring the Efficiency of an Absorptive Muffler Design

Bridget Cunningham | December 30, 2015

Mufflers are used for acoustic soundproofing in combustion engines and HVAC systems. Before achieving optimal performance, a muffler design can go through several iterations. COMSOL Multiphysics provides a flexible environment for testing different designs, saving time and costs while ensuring high performance. Now, with simulation apps, each modification no longer requires the help of a simulation expert. Instead, colleagues can run their own tests and deliver faster results to customers. Our Absorptive Muffler Designer demo app offers insight.

The demand for better performance and increased accuracy in touchscreen devices is growing. Simulation, a fast and cost-effective approach to product development, helps to meet this goal. With each design modification, colleagues will typically rely on you to run simulation tests, awaiting your feedback before reaching out to customers. As researchers at Parade Technologies (formerly Cypress Semiconductor) have discovered, creating apps and distributing them to colleagues is a valuable way to save time and more effectively communicate with customers.

Silicon chips have been the foundation of power electronics over the years. However, as more applications are using increasingly higher amounts of electrical power, silicon has begun to reach its limits. Wide band gap semiconductors offer an opportunity to surpass these confines, operating at high frequencies, voltages, and temperatures. Looking to optimize their development of wide band gap solutions, engineers at Wolfspeed utilized the power of the Application Builder within COMSOL Multiphysics.

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.

Previously on the blog, we introduced you to the constructal law, the law of physics that accounts for the natural tendency of designs to evolve freely over time to flow more easily. As research has been conducted to support this pattern of design evolution, an even greater phenomenon has come to light: Humans and technology are one species, evolving together.
