How to Guides

Posted by Nazita Saye

Nazita Saye I’d like to think of myself as a pretty competent person – throw a problem at me, I’ll find a solution for it. Case in point. Last week I noticed some cracks suddenly appearing in the kitchen walls and ceiling. The kitchen sits directly underneath the bathroom. The cracks looked like they were appearing where the bathtub was located and they felt damp. Doesn’t take Sherlock Holmes to deduce this … Read More

John Parry SEMI-THERM is one of the premier thermal management conferences and has the most targeted exhibition by far, with some 40+ exhibitors, including Mentor Graphics as Platinum Sponsor, so it’s a great place to network with people in the ‘cooling business’. The exhibition is FREE TO ATTEND, so if you’re in the bay area and interested in thermal management stop by and see us at the DoubleTree Hotel and … Read More

What is Fluid Thinking?

Posted by Doug Kolak

Doug Kolak Do you know someone who had issues with an automobile overheating or an issue with a sump pump?  What about someone who has flown on an aircraft or even used electricity?   If I had to take a not so wild guess, I would bet that most people out there with the ability to read a blog post would answer yes to at least one of these questions.  This is good because it means you have at least indirectly … Read More

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 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 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

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
