Fans are probably the most commonly used machines - from
computers to power station boilers, they come in all shapes and
sizes. In today's ever more demanding marketplace companies
are evolving fans that are more efficient, quieter, and cheaper to
run.
These IMechE event transactions bring together international
authors presenting their latest research and development. With
significant developments, such as the impact of CFD on fan design
and the increasingly common application of variable speed,
International Conference on Fans provides a unique
opportunity for both manufacturers and users of fans to share their
experience and findings.
Topics include:
* Noise and vibration
* Small fans and motors
* Computational fluid dynamics
* Cooling applications
* Operation and maintenance
* Impact of technology, legislation, and testing
* Fan design
International Conference on Fans is vital reading for fan
users, installers, consultants, and manufacturers and everyone
concerned with power generation, industrial processes, commercial
ventilation, air conditioning, tunnel and mine ventilation.
