Robin Bornoff Have you ever wondered why, after a winter night, some of your car windows are iced over whilst others are not? Happens after a clear night with no clouds. To understand the reason one must appreciate the fact that something loses heat, and thus gets cold, for two reasons; losing heat to the local air by convection and losing heat to any colder surrounding object due to thermal radiation. On a cold … Read More

FloVENT, Heat Your Home Office for 8p a Day, CFD, HVAC, thermal comfort

27 Nov, 2013

Robin Bornoff Dylan in his original YouTube video made the point that the tea lights only burn for about 4 hours and that he replaces them after the morning burn for an afternoon warm up session. At 1p per candle, 1p/~35W, we shouldn’t lose sight of how cost effective this heating method is. There is some doubt as to the actual power dissipation for each candle but this approach is scalable, if a 4 candle arrangement … Read More

Robin Bornoff We often do things that we intuitively feel are beneficial, often without realising just why. One of the beauties of simulation is its ability to provide insight into a physical phenomena or design. Sometimes described a a computational experiment, simulation can do more, and more easily, in terms of ‘measuring’ a system. I’ve applied this advantage to help describe why putting a couple … Read More

18 Nov, 2013

Robin Bornoff Dylan Winter, boat owner, film maker and blogger, made a youtube video about a year ago showing how four tealights (small candles) can be used to warm up a small well insulated home office. A couple of weeks ago the video went viral, now having ranked up nearly 2.5 millions views. A couple of friends pinged me to see if I could help explain why this apparent miracle in home heating worked. Some pacing … Read More

Happy 25th FloTHERM

Posted by Nazita Saye

Nazita Saye In this day and age where products come and go in a flash it is a great honor to be involved with something that has successfully passed several major milestones. Twenty-five years ago, Flomerics opened its doors and FloTHERM moved from being a glimmer in the minds of Drs. Rosten and Thatchell to something real. The team of idealists had very definite thoughts when they sat down to create FloTHERM. … Read More

Future Phone

Posted by Nazita Saye

Nazita Saye You all know how gadget-mad I am, right? Well guess what’s got my senses buzzing today? A mobile phone that you can build yourself from various components … something akin to a Lego phone and it’s called the Phoneblok. A Dutch designer, Dave Hakkens, came up with the idea after he wanted to replace a single broken component in his mobile phone. When he was told that he couldn’t just replace the broken … Read More

Design Based on Assumptions

Posted by Nazita Saye

Nazita Saye I recently read an article about the Soviet space shuttle program which I found absolutely fascinating. We all know about the rivalry between the Americans and the Russians during the cold war so nothing new there. But what I found fascinating was how the Russians made a series of assumptions about the American space shuttle program based on information gleamed from various sources. And unfortunately, … Read More

Light My Way

Posted by Nazita Saye

Nazita Saye My last blog post about trash cans on London streets turned out to be quite controversial. It wasn’t my blog post that caused a furor but I guess a few other folks in London were on the same wavelength as me when they came across these bins. In case you missed my last post, here’s a quick summary. A company in England has tricked out a whole network of trash cans in London with LED displays that serve … Read More

CFD - Colourful Friday Distractions

Posted by Robin Bornoff

Robin Bornoff By way of an apology for the more verbose blogs I’ve been issuing recently I’d like to present you with a blog that serves no other purpose than to show a pretty picture. CFD as an acronym has quite a few different interpretations. Contracts for Difference if you’re into your financials. Colour For Directors if you’re in marketing. Cheats, Frauds and Deceivers if you’re … Read More

5 Apr, 2013

Robin Bornoff Electronics cooling simulation was born out of the world of CFD, rather fully conjugate heat transfer simulation where convective, radiative and conductive affects are considered concurrently. Back in the day much talk was had about turbulence modelling, convective discretisation schemes and linear equation solvers, all typical CFD subjects but somewhat out of place in the context of what became the … Read More

Some Like it Hotter

Posted by Nazita Saye

Nazita Saye You all know what a chatterbox I can be when I’m excited about something. So believe you me when I say the past few months have been excruciatingly hard for me. I’ve been sitting on some pretty big news and I’ve been itching to tell the world all about it.  Now that the cat is officially out of the bag, there’s no holding me back… FloTHERM XT as the enabling technology in the EDA/MDA design flow. The … Read More

Data Center Presentation at ASME in Texas

Posted by Travis Mikjaniec

Travis Mikjaniec Hello Everyone This is a bit of a follow up to my previous blog about the FloVENT analysis of the Mentor Graphics Data Centers in Wilsonville, OR and Shannon, Ireland.  http://www.mentor.com/products/mechanical/blog/post/mentor-graphics-data-center-design-using-cfd-modeling-fc6dbfc3-ec40-431a-8628-67375c2e946a Well the one in Shannon, Ireland has been online for a while now, and our Wilsonville, OR data … Read More

Travis Mikjaniec Hello Everybody   Previously, I co-authored a semitherm paper on the use of our HVAC CFD tool, FloVENT, on the design of a Mentor Graphics data center.  Recently I have seen this topic republished in the data center journal with the title “EDA Vendor takes its Own Advice on Data Center Design”.  I find this topic interesting, so I thought I’d blog about this and break from my typical … Read More

Shrink It and Pink It

Posted by Nazita Saye

Nazita Saye I’ve never really been a fan of the color pink. If you look thru my childhood pictures you’ll find me wearing pink clothes (chosen by my lovely mom) but in every one of those pictures you also find my head slightly dipped down, defiantly looking into the camera and pouting. Not a happy bunny. As soon as I was old enough to make my own decisions regarding clothes, pink was banished from my wardrobe. … Read More

"Why Cartesian Grids Are Good"

Posted by Robin Bornoff

Robin Bornoff I put the title in quotes as it’s the title of a blog post by John Chawner at Pointwise who keeps a pleasantly vendor neutral(ish) blog about all things CFD called ‘Another Fine Mesh’, including the excellent weekly ‘This Week in CFD’ that is becoming a bit of a mecca for the CFD community. John’s blog focusses on a white paper Mentor issued recently about How to … Read More
