[YouTube] Balloons and Dyson Air Multiplier™ fans

One balloon and a couple of evenings after work — Dyson engineers show how inducement and entrainment works on the Air Multiplier™ fan. If you watch closely, the balloon is sucked into the airflow from behind and to the side of the fan; this is inducement and entrainment of the air.  Lots of experimentation with different sized balloons and other objects produced this video. And although edited to include our successful attempts, the video is made from completely genuine footage (and no, the balloon isnt attached to anything). Find out more at: www.dyson.com/fans  Disclaimer: This was created and executed by trained Dyson engineers under a controlled environment. Do not attempt to duplicate.

ちなみに、このダイソン・エアマルチプライアーの仕組みは意外とシンプル。輪っかの土台部分が空気を吸い込み、輪っかの前面からその空気を放出。放出された空気の流れによって周りの空気も誘導され、吸い込んだ空気の量の15倍の空気が前面に押し出されるようになっているとのこと。創業者ジェームズ・ダイソンさんの解説動画がこちら。
