One of the more significant obstacles to automotive start-stop systems is how to keep the car comfy with the engine off. Saving fuel is great, but not if the infotainment system, HVAC et al were to shut down at every red light.
At the SAE World Congress in Detroit last week, Delphi Automotive introduced a Phase Change Material (PCM) Evaporator that it said will keep start/stop vehicle cabins cooler … Read More

Over the weekend I realized I have become English. No, I haven’t picked up the accent. Nor do I eat Marmite. Actually eating Marmite can be relegated to one of those things I’d never do. Never, ever. So why have I become English? I tend to discuss the weather and temperature … Read More

In 1989 Flomerics was the first organisation to provide application specific CFD based simulation software where all pre and post-processing capabilities were contained within a single WIMP based graphical user interface. That pioneering period involved missionary sales to add simulation to the arsenal of the design engineer, enabling virtual prototyping to be used as a precursor to physical build and … Read More

The UK government has a policy for all year 10 or year 11 students to undertake a week’s work experience. Last week we welcomed a 15 year old student to the Mentor office where the FloTHERM and FloVENT software development is done. The student was tasked with simulating the air flow and temperature distribution in the office space using FloVENT. Using our own software to model our own offices … Read More

What do you call someone who doesn’t believe in Father Christmas? A rebel without a Claus. Right, that’s that out of the way. This week Facebook announced that it plans to build a 300,000 ft^2 data center in Lulea, Sweden. The Lulea business agency who helped attract Facebook to their city are dutifully excited as should Facebook be as they look set to capitalise on 10 months each year of … Read More

It would only have cost me an extra £170, a small extra compared to the cost of the rest of the build, but I decided against laying thermal insulation boards directly under the underfloor electric heating mats. Surely better to leak some of the heat down to heat the 100mm thick concrete screed which would maintain its heat through those cold winter weeks, giving thermal support to the heating mats in … Read More

3D simulation can provide a detailed prediction of temperature and heat flux values at 10s of 1000s of points in a 3D model, experimental methods are somewhat limited in terms of the wealth of data they are capable of providing. But hey, this isn’t going to degrade into a pitched battle between simulators and experimentalists, nowadays good engineers (should) do both. “No one believes simulation … Read More

It’s been over two years since the foundations went in for the extension we’re building on our house. In that time I’ve come to respect and somewhat rely on glib phrases such as “Good things come to those who wait” and “Patience is a virtue”. I told my better half we’d be moved in by Christmas, I didn’t say which one though. In this blog series of … Read More

Welcome to Part IV of a multi-part series, where in this installment Travis continues the “virtual” look at his crawlspace.
In the previous installment of “this old CFD house”, we started to peel back the veil on my crawlspace and its moisture issue. I analyzed the problem as it is, and we made some enlightening findings. First, really the only way air is getting into the crawlspace is … Read More

Welcome to Part III of a multi-part series, where in this installment Travis takes a “virtual” look at his crawlspace.
For this next installment of “this old CFD house”, and really the entire reason I started this blog series, I’d like to take a look in my crawlspace. Now, from what I understand, Feng Shui says running water is good for wealth. Well the opposite is true when you have … Read More
