Engineering Love

Posted by Robin Bornoff

Robin Bornoff It’s National Engineer’s Week in the US this week. A similar event takes place in the UK in March. I’ve been lucky enough to have been an engineer (mechanical) for my entire career and long may it continue! However I didn’t start out enthusiastic about engineering at all. When I was young I never really had an interest in renovating cars, fixing engines or taking things apart … Read More

The Unknown Engineering Hero

Posted by Nazita Saye

Nazita Saye I don’t know about you but I used to break into a sweat when I’d meet someone new because invariably they’d ask the question. What do you do? Since I love what I do, I’d always go into a speech about computational fluid dynamics (CFD) until a chance occurrence at a party made me change my behavior a few years ago. At his birthday party, an English friend of mine introduced me to one of his friends who … Read More

Robin Bornoff A full 3D thermal simulation of an electronic system requires, not surprisingly, a 3D geometric representation of the proposed design. Much of the design data for a phone, laptop, blade server, IGBT cooling system etc. often already resides in an MCAD system and is readily importable into FloTHERM or loadable into FloTHERM XT. EDA design data, be it a PCB layout or BGA substrate, is often held in 2 … Read More

BHRA Test Facilities

Posted by Don Miller

Don Miller Commissioning BHRA Test Rigs Having recently joined the project team at BHRA that was to develop a design guide for loss coefficients in large scale flow systems, I had the opportunity to commission the new test rigs that we would be using.  From experience I knew that bringing a new wind tunnel online could take months before conditions were acceptable in the test section; however I certainly underestimated … Read More

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
