Wind tunnel testing was considered of strategic importance during the Cold War development of supersonic aircraft and missiles. Later, wind tunnel study came into its own: the effects of wind on man-made structures or objects needed to be studied when buildings became tall enough to present large surfaces to the wind, and the resulting forces had to be resisted by the building's internal ...

Grinding in small plants, as in larger installations, has proven to be the most costly of all unit operations from both capital and operating standpoints. Therefore, grinding deserves the most scrutiny of all operations during the design procedure. A recent survey by a major grinding mill manufacturer reveals that more than 80 autogenous or semi-autogenous mills having between 100 and 1,000 ...

The wind tunnel has a wooden exoskeleton for rigidity. The exoskeleton frames three sections: the compression section, test section, and exhaust section. The compression section's frame is lined with smooth plastic sheeting and is boxed-in on the top and bottom by sheets of plywood. The plastic sheeting is stapled to the exoskeleton and all corners and edges are smoothed with Silicon II ...

Planes, cars, bikes, and many other objects are used in wind tunnels to test aerodynamics, or how an object moves through air at many speeds. For bikes and cars, we want them to be pushed lower into the ground (no lift), whereas with airplanes we want them can to create lift so they can fly through the sky. Wind tunnels can be whole buildings which use powerful fans to test life size objects ...
