The design of fans has evolved to meet the ever-increasing demands for higher efficiency machines, combined with the requirements for lower noise and high availability. In addition many fans are now being used in safety related applications, such as smoke control in buildings and underground spaces in the event of a fire. Variable speed is now more common, leading to some additional design problems and many existing users are revisiting their plant looking at ways to upgrade the fans.

The use of numerical simulation techniques is also becoming an established part of aerodynamic design processes. Following on from the very successful Fan 2012 conference, this event will be a forum for fan and system designers, manufacturers and operators, with the aim of improving our understanding of fans and their system interaction.

This three-day conference will include keynote lectures and technical presentations. The technical presentations will be organised as three tracks (see below) for fans in non-aerospace applications. All types of fans, such as those used in industrial process, HVAC, electronic equipment, household appliances, automotive and traction fall within the scope of the conference.
