Lowering Water Levels by not Taking Away the Water

Phil Kinnane July 17, 2012

Düsensauginfiltration (DSI) is a novel technique for lowering water levels at mining and construction sites while not actually having to transport the water away from these sites. This came to my attention at the latest COMSOL Conference in Stuttgart. There, Ph.D. student Yulan Jin and Assistant Professor Dr. Ekkehard Holzbecher from the Georg-August University in Göttingen, Germany was presenting their research into this groundwater lowering technique.

David Kan has previously blogged very well about the Pipe Flow Module, where he described the fundamentals behind this new product of ours. Now, you can see this module in action at a webinar run on July 19th. Check out the details and registration for the upcoming Pipe Flow Simulation Using COMSOL webinar.

Transformers were first commercially used in the late 1800’s, but they are still being investigated at their fundamental levels. One of the stories from our latest COMSOL News concerns ABB (who themselves have been around since the late 1800’s) and their research into these apparatuses.

During the last few months, we have been offering “lunch time tutorials” for users and others interested in multiphysics modeling. In these webinar-run tutorials, we choose an application and spend a bit of time looking at it, and how to model it in detail. We’ve already reported about an example that models a gate valve and now we are ready to offer an example related to pollution, namely that of a particle plume that spreads throughout a room.

I have just come back from a bit of a vacation and boy was it hot! Here, a large part of the US has been going through record high temperatures and most of my time was spent trying to keep cool. How nice then to mention a story about cooling.

In an earlier blog post, I commented on how acoustic waves are being used in a biomedical setting, to identify malaria in small fluid samples. A more traditional use of piezoelectric devices was written about in the latest COMSOL News. Here, an Italian company, Esaote S.p.A., uses them to produce improved ultrasound imaging systems.

One of the interesting stories to come out of the latest COMSOL News concerned a couple of great researchers, Dr. Ozgur Yildirim and Dr. Zihong Guo, and how they use simulations in their inventing process. They work in an invention/prototype laboratory in Bellevue, WA for Intellectual Ventures, a global leader in the business of invention.

I have always connected Surface Acoustic Waves (SAWs) as phenomena useful for sensors; where SAW devices act as the medium that transfers mechanical energy (of what you’re measuring) to electrical (what’s used to measure it). SAWs would occur at the surface of a piezoelectric device, mechanically changing it, and then the resulting electrical behavior would be used to provide the measurement. We have a great example that shows how such things can be modeled in a SAW gas sensor.

According to a study done by Brunel University in the United Kingdom, the food sector is among the top five energy-consuming industries. The transportation of food, including keeping it refrigerated, is one of the larger contributing factors to this energy-consumption and subsequent greenhouse gas emissions.
