  • Wind turbine - Wikipedia

    2021-9-5 · A wind turbine is a device that converts the wind's kinetic energy into electrical energy.. Wind turbines are manufactured in a wide range of sizes, with either horizontal or vertical axes. It is estimated that hundreds of thousands of large turbines, in installations known as wind farms, now generate over 650 gigawatts of power, with 60 GW added each year.

  • 3D printing - Wikipedia

    2 days ago · 3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. The term '3D printing' can refer to a variety of processes in which material is deposited, joined or solidified under computer control to create a three-dimensional object, with material being added together (such as plastics, liquids or powder grains being fused ...

  • Boundary layer - Wikipedia

    2021-9-2 · Laminar boundary layers can be loosely classified according to their structure and the circumstances under which they are created. The thin shear layer which develops on an oscillating body is an example of a Stokes boundary layer, while the Blasius boundary layer refers to the well-known similarity solution near an attached flat plate held in an oncoming unidirectional flow and Falkner–Skan ...

    to reach the inner end of a typical compressor, it has been squeezed into a space 20 times smaller than the intake aperture. Expanding as it leaves the high-pressure compressor, the air enters the combustor, an interior engine cylinder in which the air will be mixed with fuel and burned. The combustion chamber is actually a ring, shaped something like a car's air filter.

  • 4 Ways to Calculate Wind Load - wikiHow

    2020-5-25 · Calculate wind pressure. The simple formula for wind pressure P in imperial units (pounds per square foot) is =, where V is the speed of the wind in miles per hour (mph). To find the pressure in SI units (Newtons per square meter), instead use =, and measure V in meters per second.. This formula is based on the American Society of Civil Engineers code.
