Fluid Machines are equipments capable of producing useful effects by means of energetic interactions with fluid streams.

The fluid machines are classified in two types:

• Driving Machines
• Handling Machines

Driving Machines extract energy from fluid streams and make it available from a rotating shaft.

Handling Machines transfer energy to fluids with purposes of transportation and/or pressurization.

The more used fluid machines in industrial services are:

• Fans
• Pumps
• Compressors
• Turbines
• Internal Combustion Machines

The main obstacle encountered by those interested in dealing professionally with fluid machines is the need of a reasonable amount of knowledge on several different engineering areas.

Just to quote the most important ones:

• Basic Physics
• Thermodynamics
• Fluid Mechanics
• Instrumentation/Control
• Materials Properties
• Materials Strength/Stress Analysis
• Mechanical Vibrations
• Manufacturing Processes
• Lubrication
