Compressors, Fans & Blowers – Basic Understanding

Compressors, fans, and blowers are widely used in various industries. These devices are quite suitable for complex processes and have become indispensable for some specific applications. They have been defined in simple terms as below:

  • Compressor: A compressor is a machine which reduces the volume of gas or liquid by creating a high pressure. We can also say that a compressor simply compresses a substance which is usually gas.
  • Fans: a Fan is a machine used to move fluid or air. It is operated through a motor via electricity which rotates the blades that are attached to a shaft.
  • Blowers: Blower is a machine to move air at a moderate pressure. Or simply, blowers are used for blowing air/gas.

The basic difference between the above three devices is the way they move or transmit air/gas and induce system pressure. Compressors, Fans & Blowers are defined by ASME (American Society of Mechanical Engineers) as the ratio of the discharge pressure over the suction pressure. Fans have the specific ratio up to 1.11, blowers from 1.11 to 1.20 and compressors have more than 1.20.

In this tutorial you will learn to simulate a Blower using Ansys Fluent. You can download the geometry from this link.

The NACA four-digit wing sections define the profile by:
First digit describing maximum camber as percentage of the chord.
Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord.
