Investigating Damage to Cultural Heritage Sites with Simulation

Caty Fairclough | May 3, 2016

Why are the famous paintings on the walls of a Netherlands chapel deteriorating? To answer this question, researchers from the Eindhoven University of Technology used physical measurements and simulation to evaluate how rising moisture affects the chapel’s artwork. Today, we’ll see how their research helped provide a better understanding of the damage occurring within this cultural heritage site.

Graphene is a material with a strong presence — and impact — throughout the scientific community. Amongst its many uses, researchers are looking to graphene as a potential material solution within sensor designs for medical and biosensing applications. Today, we’ll explore the role of simulation in analyzing and optimizing a 3D multilayered graphene biosensor.

We’ve talked a lot on the blog about the different types of simulation apps that you can build. But did you know that you can create an app that plays sounds? The Organ Pipe Designer allows users to investigate the parameters behind an organ pipe configuration and then play the resulting sounds to really see — and hear — a design in action. Let’s learn more about the physics behind our underlying model and its transformation into an easy-to-use app.

Radiators, refrigerators, and geothermal pumps all need to efficiently extract heat from one fluid to another without mixing them. Among all of the different heat exchanger designs, finned pipes aim to increase the exchange surface between the content of a pipe and the exterior using fins. Finned pipes usually show a geometrical periodicity along the length, which we will take advantage of in this demo app to reduce computational costs.

Two professional chefs stand in a classroom, closely observing a soft-boiled egg. What may initially sound like a cooking class is actually part of a physics course offered at the Technische Universiteit Eindhoven (TU/e) in the Netherlands. Using COMSOL Multiphysics, students are investigating the science behind cooking the perfect soft-boiled egg. See how this innovative blend of simulation research and food science is teaching students how to build and test models.

Whenever solid materials are heated enough, they will melt and then vaporize to a gas. Certain materials will even go directly from the solid to the gas phase, a process referred to as sublimation or ablation. If the material is heated strongly enough, there will be significant material removal. Today, we will look at how you can model this process in COMSOL Multiphysics.

When designing tall, slender truss towers topped with heavy loads, engineers may want to account for buckling. This requires calculating the critical compressive load of the structure at hand. Simulation is a time- and cost-efficient way to generate such results. Now, with simulation apps, this process is becoming even faster. Those without simulation expertise can easily run their own tests to calculate the critical compressive load for different truss tower configurations.

Over the 10th through 18th centuries, the sound holes in violins evolved from a circular shape to an elongated f shape. In a recent research paper, MIT scientists and violin makers from the North Bennet Street School in Boston investigated the effects of this change in shape. They suggest that the f-shaped holes increase the air flow, making the bass notes of the violin twice as loud. Today, we will reproduce their findings with COMSOL Multiphysics.

Pressure vessels are designed to confine liquids or gases. These containers are used in nuclear plants, throughout the chemical and petroleum industries, and even as water heaters in homes. In principle, the vessels’ internal pressure is much higher (or sometimes lower) than the ambient pressure, so the vessels must be carefully designed, as failure can result in severe damage. Today, we’ll show you how to use the Application Builder in COMSOL Multiphysics to create an efficient and accurate design workflow.

Continuing his discussion of simulation apps, guest blogger Mehrzad Tabatabaian presents an app that he designed to study transient heat transfer in a nonprismatic fin. In earlier blog post, I spoke about my new book, COMSOL5 for Engineers, a resource designed to inspire and guide the creation of COMSOL models and simulation apps. Today, I’ll share a model with you that I created to analyze transient heat transfer in a fin as well as its corresponding app.
