Impeller Design Analysis Using CFD Software

Computational Fluid Dynamics (CFD) is the use of mathematics, physics and computational software to visualise how fluid flows. It also looks at how the fluid affects objects as it flows past...

The Rules to Make Sure Your Fan is a Failure!!

We know sometimes things are all a bit too serious, so this issue we have decided to address the critical issue of industrial fan specifications and technical details with a touch of humour, but...

Is your fan built to last?

The rotating component of a fan is called an impeller, and is arguable the most important part of the fan. The impeller is designed from fluid dynamic specifications such as volume flow and pressure...

greenhouse gas emissions

Greenhouse Gas Emissions

Did you know that air weighs 1.2 kg per cubic meter and when a fan moves this weight of air energy is required. Take an average Powder Coating Booth with a Reverse Pulse Dust Collector. ...

Breakdown Service

Recently "A" customer, who shall remain nameless, and who runs a large manufacturing concern had to meet a very critical chronological & geographic requirement (he had to be at a cricket match ...

powering your fan

Powering Your Fan

At Morse Air Systems we are constantly coming across power problems brought to us by our customers. Here are a few of them to show not only the sorts of problems that can arise but what ...

the air we breathe

The Air We Breathe!

Spare a thought for the air that we breathe. As humans, we breathe normally at approximately 6 litres of air per minute. This equates to about ½ kilogram of air per hour. ...

noisy fan

My Fan is too Noisy

These days noise is an important environmental and OH&S issue. For the most part when dealing with fans it is the “rush” or roar at an inlet or outlet that is the problem. ...

What is a Fan - Fan Laws

Part 1 in a Technical Series by Michael Morse. A fan is a volume machine that shovels air. The bigger the shovel the greater the air flow. Fans are predictable and follow a strict set of laws. ...

critical speed of shafts

Critical Speed of Shafts

The critical speed is the theoretical angular velocity which excites the natural frequency of a rotating object, such as a shaft. As the speed of rotation approaches the objects natural frequency, ...

fan fatigue crack

Fan Resonance - Other Failure Modes

In previous issues we have talked about natural frequencies as applied to the shaft /impeller assembly. There is another issue that can sometimes lead to problems in operation, ...
