Fluid Flow in Ceramic Matrix Composites In a previous Blog we discussed some of the background to the production of Ceramic Matrix Composites (CMCs) using the Reactive Melt Infiltration (RMI) process. In this Blog we will address some of the issues associated with the first step in the process: infiltration of molten material into a

Create the Future Design Contest 2014 Since 2002, NASA Tech Briefs has been stimulating and rewarding engineering innovation through the Create the Future Design Contest. During that time, the annual event has attracted more than 8,000 product design ideas from engineers, entrepreneurs, and students worldwide. And in recent years, it has attracted us, with

COMSOL Training – The Truth About Our Classes We readily accept that our COMSOL Training classes are not for everyone, especially with COMSOL doing such a good job. The training calendar is ready for the first half of next year, and we are now registering for our classes. Check it out using this link. Some
Ceramic Matrix Composites: Background We are often asked “What do you mean by fully coupled multiphysics simulations?” By way of answering this question we are providing a series of Blog articles that will explain the background to a fully coupled multiphysics simulation using a direct example on simulating the processing of ceramic matrix composites (CMC),

Heat Sink Design In last month’s Blog we discussed alternative techniques for increasing the amount of heat dissipation in electronic circuits and components. One of the most commonly used approaches to increase heat dissipation is the use of heat sinks. Heat sink design seeks to maximize the surface area in contact with the surrounding
Widgets, Plug Ins and Social Media (All the way) Back in 2013, we decided to rebuild our website. We had previously evaluated our site in light of Our Mission and Values and decided we could make some improvements. So we got some new widgets, and some new plug ins, and all the other bells and

COMSOL Tips & Tricks – Text-Based Search Filter Many of us are running Multiphysics analyses with COMSOL. And, of course, the more physics we are solving for the more variables we have available for post-processing. Maybe you are like me and have gotten lost in the sea of available variables when clicking on the

Thermal Mitigation – Common Approaches If the operating temperatures remain outside the prescribed thermal budget established for safe device and component operation we are now faced with two options: either reduce the power levels that may change device functionality or increase the dissipation of heat to reduce the standard operating temperatures. In some
