Liquid electrolytes (i.e. acids and bases) can be used to pattern metal and semiconductor surfaces. The removal process is an electrochemical surface reaction that is often dependent on reactant and product concentrations, therefore non-homogenous etch rates are common. STAR-CCM+ can be used to aid understanding and optimization of wet-etch processes by predicting these concentration dependent etch rates. The above images show etch-product concentration and etch profiles along a copper surface at the bottom of a two-dimensional trench.
CD-adapco tools are used by a number of fuel cell companies to understand and optimize both proton exchange membrane (PEM) and solid oxide (SOFC) fuel cells. The image shows a single cell SOFC that incorporates heat transfer, electrochemical reaction, and multi-component gas transport.
Research at MIT has shown that ionic wind can produce 55 times more thrust per kilowatt than traditional jet engines . This type of airflow can be produced by applying a voltage between two electrodes. If one electrode is sharp enough (like a wire or blade), a corona discharge occurs near the electrode surface that ionizes certain gas species (often O 2 + in air). These charged ions migrate from one electrode to the other, resulting in air flow.
Automotive companies utilize electroplating to make plastic parts look like metal. In the above image, Chromium III plating thickness on a plastic automotive grille is predicted using secondary current distributions. Chromium plating is the final layer in a multistep electroplating process consisting of pretreatment, copper, nickel, and finally chrome deposition. Choosing locations to make electric contact with the plastic part is crucial in obtaining evenly distributed films.
Recently, I sat down with Alex Smith from the Centre for Process Innovation (CPI), a UK-based technology innovation centre that uses knowledge in science and engineering combined with state-of-the art facilities to enable their clients to prototype and scale up the next generation of products and processes. Alex is a recent recruit who is just approaching his first work anniversary with CPI. He is a Senior Process Engineer within their Industrial Biotechnology and Biorefining (IB&B) unit and it hasn’t taken him very long to get his hands dirty with simulation work. He is currently balancing his time mostly between developing their CFD capability, both in model development and training of future users, and working on some more 'standard' process engineering tasks such as plant improvement and troubleshooting exercises.

Cell Can to Battery Module: Boost HEV Battery Performance Through Simulation
This two-part webcast will show attendees how to improve the specifications of a commercially available cell and simulate the performance of an HEV battery module using Battery Design Studio® and STAR-CCM+/Battery Simulation Module™ software. Utilizing cutting-edge technology, this webcast will help demonstrate how you can derive real benefits. Within the webcast, the characterization process is explained to highlight and explore the key parameters necessary for the cell performance model. Presenters examine how technology like Battery Design Studio can quickly and accurately adjust cell...
Fluid Film Coating Simulation
In our example the part is dipped into a VOF bath using Overset Mesh to model the motion, on being pulled back out of the bath it picks up a Fluid Film coating, and we can see the resultant thickness (as shown by the scalar on the surface) is far from even – perhaps we need to change our dipping process. As the film runs down the part, it drips off as Lagrangian droplets, and the droplets finally drip back into the VOF bath (thanks to the Lagrangian-VOF multiphase interaction model). This example took 12 hours on 10 cores, orders of magnitude less than would have been required for a resolved...
When asked about the amount of time he spent on his speech preparation, Woodrow Wilson responded: “That depends on the length of the speech. If it is a ten-minute speech it takes me all of two weeks to prepare it; if it is a half-hour speech it takes me a week; if I can talk as long as I want to it requires no preparation at all. I am ready now.” Perhaps some of us can relate to former President Wilson’s remarks. Without any time constraints, exploring a .sim file, or maybe several, in detail, could be an engaging and informative exercise lasting the better part of an afternoon. Yet more often than not, we only have that brief ten minutes to share our story. And, quite often, review requests come on short notice. What if you could quickly assemble and effectively communicate your results from several simulations in a matter of minutes? What if you could walk from one meeting room to the next, with laptop in hand, and be able to quickly collaborate with different teams? As it turns out, there is a way: STAR-View+, new and improved.
CD-adapco™, the largest privately held CFD-focused provider of Computer Aided Engineering software, today announced the release of STAR-CCM+ v10.02, the latest version of its flagship simulation tool. Focusing on Multidisciplinary Design eXploration (MDX) to help accelerate the design decision process, this release allows engineers to drive their simulations through a complete range of operating scenarios. This approach can be used to gain a complete understanding of the performance of a product across the whole design space.
