Robin Bornoff Simulation should never be done for its own sake. 3D computational simulation is still a relatively young technology in the grand scheme of things, akin to the automotive industry of 100 years ago where drivers were more like engineers, they had to be to use the car. Coming up with a design solution is analogous to getting to your destination in a car, it’s also quicker than walking. That’s … Read More

Things I learned in 2013

Posted by Nazita Saye

Nazita Saye Sharon, one of my friends, jokingly (but with a sinister tone in her voice) calls me the List Maker. And it’s true. Somehow making lists and crossing out items makes me feel a bit more in control of my life where the only theme is constant change. On the first day of my Christmas vacation I made a list of everything that I needed to do around the house… stuff that is time-consuming and requires more … Read More

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

Robin Bornoff It’s always nice to get some comments on your blog. When starting writing blogs about 4 years ago I was told that so long as you write about something that you’re interested in, then others will read it. Comments are the echo to what otherwise would be a Demosthenes type shouting at a roaring sea of disinterest. So when a colleague here at Mentor, Dave Roberts, commented on Part 3 of this … Read More

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

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 Birthday FloTHERM !

Posted by Robin Bornoff

Robin Bornoff Late in 1988 two key employees of CHAM (Concentration Heat And Momentum Ltd.), the first commercial CFD vendor and at the time market leader, left to set up a new type of CFD company. Recognising the opportunity to package CFD in focussed, highly automated and application specific products, David Tatchell and Harvey Rosten started to develop what would become FloTHERM. A CFD simulation tool targeted … 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

Thanksgiving Turkey Analysis in FloEFD

Posted by Travis Mikjaniec

Travis Mikjaniec Hello Everyone It’s been a while since my last blog as it’s been a very busy year.  One blog topic I’ve been wanting to do for a while is look into roasting turkeys.  Let me explain.  My wife is not very good at cooking American food.  Well I likely don’t need American in that sentence.  So when we moved into our house, and started our family, one of the issues that I needed … 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

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

Brave New World?

Posted by Nazita Saye

Nazita Saye I live and work in the burbs but I go into London every week. I usually hang out where my friends live. But from time to time work takes me to the square mile. The square mile is where most of the financial services industry is based in London. On days where I find myself in that neighborhood I feel like a country bumpkin. You see I tend to walk just a nudge slower than the masses – I’m used to … Read More

Robin Bornoff An appreciation of heat flow paths is a pre-requisite for good thermal design. If you attempt to augment heat flow where there is none then your expectations are as futile as your design skills. The real value of simulation for me is that it enables an insight into the behaviour of a proposed design (this is true for simulation of any design and any behaviour). Once you understand the true physics of … Read More
