"I was turning the page to get ready for the next page, but the draft wind from the turn caused the spare pages to fall off the stand," Mr. Titterton said, "Luckily I was able to catch them and put them back."

This paper studies the influence of cross wind on the performance of natural draft dry - cooling tower by means of model experiment and numerical simulation.

The influence of cross wind on the air flow field in a natural draft dry cooling tower is studied experimentally on the basis of similarity rules.
