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.
The IMechE is the United Kingdom's qualifying body for mechanical engineers and the home of mechanical engineers for over 150 years. Around 75,000 engineers world-wide are members.
