One of his first projects at Collins was the design of a high-speed smoke tunnel.

Experiments were carried out in a low speed wind tunnel and a smoke tunnel.

Still, the drills felt more like a county fair than like a war zone, with neighborhood ladies pouring tea for survivors of the smoke tunnel.

Lippisch's work on smoke tunnel flow visualization led to a thirteen part television series in 1955, entitled "The Secret of Flight".

Usually this is done in a special generator and the smoke is then injected into the flow, often in a purpose-built smoke tunnel.

Their cars are analysed aero-dymamically for drag co-efficiency in a virtual reality wind tunnel and are then tested in wind and smoke tunnels.

Dr. Strom worked on early versions of wind and smoke tunnels to study air pollution and smoke and fume dispersal from industrial smokestacks.

First, a "smoke tunnel" is used to teach students the components of a good escape plan, and the students are taught to "Stop, Drop and Roll" when clothing is on fire.

Within an hour, Mr. Ray's train - after a nightmarish ride downtown with overshot platforms, abrupt stops and other lurchings - jumped the tracks at breakneck speed, plowed into walls and support columns and lay in a tangle of crushed and twisted metal in a smoking tunnel near Union Square in Manhattan.
