Analyzing Utility Boiler Designs by Simulating Radiative Heat Transfer
To study a utility boiler furnace, you need to account for the effects of radiation, which is difficult to solve for analytically and study experimentally. That’s where simulation comes in.
Analyzing Novel Roof Tile Designs with Multiphysics Simulation
To investigate a novel design for roof tiles that can keep buildings cool in hot climates, called Life HEROTILE Project, a research group from Italy turned to multiphysics simulation.
Finding the Best Coal Arrangement for Even Heat in a Grill
Pizza on the grill? It’s actually quite delicious. Here, we use heat transfer modeling to determine how the grill’s coals should be arranged for even heating.
Introduction to Modeling Natural Convection in COMSOL Multiphysics®
Natural convection is a phenomenon found in many science and engineering applications, such as electronics cooling, indoor climate systems, and environmental transport problems. The CFD and Heat Transfer modules in version 5.2a of the COMSOL Multiphysics® software include functionality that makes it easier to set up and solve natural convection problems. In this blog post, we give an overview of natural convection, the new functionality, and some of the difficulties that we may stumble upon when modeling natural convection.
Optimize 3D Printers by Modeling the Glass-Transition Temperature
In 3D printers, suboptimal cooling and cure rates can negatively affect the manufactured parts and components. By optimizing a 3D printer’s design, we can ensure the quality of the printed objects. One research group used simulation to analyze the cooling process and the resulting glass-transition temperature of the polymer in a 3D printer. Let’s look at how they modeled the extrusion of acrylonitrile butadiene styrene (ABS) from a 3D printer that uses fused-deposition modeling (FDM®).
Study Sensor Performance in Rapid Thermal Annealing with Simulation
In rapid thermal annealing, a process step in producing semiconductors, measuring the temperature of a wafer is key. Without accurate measurements, overheating and nonuniform temperature distributions may occur, both of which impact the effectiveness of the process. This is why tools like the COMSOL Multiphysics® software give you the ability to analyze temperature distributions within an RTA design. From these results, you can better assess the performance of the sensor component and optimize its configuration to achieve accurate measurements.
Why Is Ice Slippery Enough for Skiing and Skating?
Finding a scientific explanation for why ice is slippery seems simple enough, but it has actually been a subject of debate and confusion for centuries. As part of the world begins to bundle up for a blustery winter, let’s explore the science behind how the slipperiness of ice enables us to ski, skate, and even fall down in the parking lot.
Why Doesn’t the Ice Cream in a Baked Alaska Melt?
One dessert that is sure to amaze your dinner guests is the baked Alaska. This classic treat consists of ice cream placed on a bed of sponge cake and covered in meringue. Although the dessert goes into a hot oven to caramelize the meringue, the ice cream inside surprisingly remains frozen. In this blog post, we use the heat transfer simulation capabilities of the COMSOL Multiphysics® software to find out how the baked Alaska works.
