tangential flow fan
1Fan (mechanical) — A mechanical fan is an electrically powered device used to produce an airflow for the purpose of creature comfort (particularly in the heat), ventilation, exhaust, or any other gaseous transport.Mechanically, a fan can be any revolving vane or… …
2Mechanical fan — Household electric box fan with a propeller style blade A mechanical fan is a machine used to create flow within a fluid, typically a gas such as air. A fan consists of a rotating arrangement of vanes or blades which act on the air. Usually, it… …
3Prandtl-Meyer expansion fan — A Prandtl Meyer expansion fan is a centered expansion process, which turns a supersonic flow around a convex corner. The fan consists of infinite number of Mach waves, diverging from a sharp corner. In case of a smooth corner, these waves can be… …
4Wood drying — (also seasoning lumber or timber seasoning) refers to reducing the moisture content of wood prior to its use. For some purposes wood is not dried at all (it is used green ) [http://en.wikipedia.org/wiki/Green wood] . Often the wood needs to be in …
5Contra-rotating — A Soviet Ka 32 helicopter with coaxial contra rotating rotors, in 1989 Contra rotating, also referred to as coaxial contra rotating, is a technique whereby parts of a mechanism rotate in opposite directions about a common axis, usually to… …
6диаметральный вентилятор — Вентилятор, у которого направление меридиональной скорости потока газа на входе и выходе из рабочего колеса перпендикулярно оси его вращения. [ГОСТ 22270 76] диаметральный вентилятор [Интент] Недопустимые, нерекомендуемые поперечнопоточный… …
7диаметральный вентилятор — Вентилятор, у которого направление меридиональной скорости потока газа на входе и выходе из рабочего колеса перпендикулярно оси его вращения. [ГОСТ 22270 76] диаметральный вентилятор [Интент] Недопустимые, нерекомендуемые поперечнопоточный… …
8Axial compressor — Axial compressors are rotating, aerofoil based compressors in which the working fluid principally flows parallel to the axis of rotation. This is in contrast with centrifugal, axi centrifugal and mixed flow compressors where the air may enter… …
9Centrifugal compressor — Centrifugal compressors, sometimes termed radial compressors, are a sub class of dynamic axisymmetric work absorbing turbomachinery.[1] Centrifugal impeller with a highly polished surface likely to improve performance …
10sedimentary rock — Rock formed at or near the Earth s surface by the accumulation and lithification of fragments of preexisting rocks or by precipitation from solution at normal surface temperatures. Sedimentary rocks can be formed only where sediments are… …
