Gimme more light

Posted by Nazita Saye

Nazita Saye I’m a perfectly good driver but I don’t enjoy driving in the dark on unfamiliar roads.  Recently I found myself driving in the dark from one village to another on a country lane in the deepest darkest Wiltshire. For those of you unfamiliar with Wilshire, it is a county in the South West of England. Here’s a picture of a typical country lane in Wiltshire. These roads are just wide enough for a car to … Read More

Robin Bornoff Energy isn’t the only thing that is wasted when dealing with hot water supply. Time is as well. The house I live in is nearly 200 years old. It wasn’t a very well made house when it was new and, unlike a good wine, has not got better with time. The retrofitted, refitted, repaired, repaired and repaired again hot water supply system would have benefited from some up front design. As it is … Read More

Don Miller When constructing a paper based on research, it is common practice to include a review of existing literature.  The idea behind including this information is to demonstrate to the reader that a certain level of thought went into the work being carried out.  Ideally armed with a thorough understanding of the subject at hand, the presented work should then build on the existing knowledge; however this … Read More

Robin Bornoff Horror vacui, Natura abhorret vacuum, Resintenza del vacuo; from Aristotle to Galileo, it has long been known that here on earth matter tends to flow from where it is to where it isn’t. Fast forward to Hobbes and Boyle, Newton and Leibniz and we find such concepts being being applied in a fluid dynamics context. From a heat transfer perspective heat energy also tends to flow from where it is to … Read More

Boris Marovic Hello to all non-believers and believers. For those of you who do not believe in Santa and are looking for ways to prove that he does not exist, this post will show you some scientific reasons why he can exist. And for those who do believe in Santa, see this as prove to your believes. As for me, well I like to believe in the spirit of Christmas and like to spend my time with family and friends and of … Read More

Robin Bornoff Sure, most modern homes have much more advanced water heating systems than a big tank with an electric heater element. Systems that work on ‘point of use’ heating concepts that heat the water as it is being delivered, not heating up a large storage container for later use. One day I hope to live in such a house! Until then I’m going to worry and fret about the amount of money spent … Read More

CFD - Toys for Boys?

Posted by Keith Hanna

Keith Hanna Being the proud father of several girls spanning in age up to 18 I am occasionally struck by something they do that hits the engineering part (or parts) of my brain. Recently, at home, I came downstairs to where my 2 year-old daughter was playing and found that she had created an interesting train out of Lego Duplo toy bricks (see below). Duplex Train created by a 2 year old girl Now, as any parent … Read More

Santa's List

Posted by Nazita Saye

Nazita Saye Santa would not be very pleased with me this year. I’ve been naughty. Yes, through an unfortunate mix of being on the road and getting ill during the past 3 weeks, I haven’t done any Christmas shopping. Nor have I sent out any cards. I keep telling my loved ones that my cards will get there … rather late for this year but being the considerate soul that I am I won’t refer to the year in my note so they … Read More

Robin Bornoff Human technical prowess relies heavily on the conversion of energy from one form to another, to meet our needs. Physiological needs underpin  Maslow’s pyramid of all our other ones. The availability of hot water is in turn important for that. Likely we’ve been heating water since the early Neolithic, converting chemical energy stored in wood to heat (radiative and convective) which in turn … Read More

Robin Bornoff A lot of engineering involves the management of energies, converting them from one form to another, channeling off useful work to power our cars, planes, phones, lights etc. To date we haven’t come up with a system to channel all energy into a desired task. Even the most advanced power generation systems still end up heating water to steam to drive turbines, a cycle that is no more than about 38% efficient. … Read More

Help from Above

Posted by Nazita Saye

Nazita Saye Drones have been around for quite some time now. More often than not, they are used for surveillance.  One major retailer has also toyed with the idea of delivering goods door to door with drones. With each announcement I can’t help but see in my mind’s eye the overcrowded skies as depicted in the Fifth Element. But I recently read a piece about drones that absolutely fascinated me. Drones for … Read More

Don Miller If we transport back to 1950s, we would find ourselves at the brink of a substantial shift in the world’s energy needs.  The current power station units simply weren’t large enough, and to meet the population’s need for power, new designs were delivering ever increasing unit sizes.  This continued until the mid-60s when the sizes stabilized but at nearly ten times the 1950s designs. As you can imagine … Read More

The Hype Around Technology

Posted by Nazita Saye

Nazita Saye My appreciation of gadgets isn’t anything that should surprise you. I’ve already talked about a few and some have proven more useful than others. For example, my Fitbit One accompanies me on every hike so I can track and then bore my friends with all kinds of useless information while some gadgets such as my waffle iron were bought rather impetuously and get dusted once every blue moon … … Read More

Robin Bornoff There are 475,000 Google search hits for ‘thermal bottleneck’. It’s a well recognised phrase playing on a very obvious analogy. Despite this there were few attempts to quantify such a parameter. Spurred on by its relevance in electronic thermal design, we did just that, put hard numbers to the concept. FloTHERM now has the ability to plot distributions of  thermal bottleneck, enabling … Read More

25 Years of Commercial 1D - 3D CFD

Posted by Keith Hanna

Keith Hanna Just occasionally in life one starts to pass all sorts of anniversary milestones, and, towards the end of this month a major one will be passed for me; 25 years associated with the commercial Computational Fluid Dynamics (CFD) scene. It still seems like yesterday that I drove my gold-colored Vauxhall Astra 1.3 litre car all the way from Birmingham to Middlesbrough in the UK with all my earthly belongings … Read More
