Abstract
С целью управлени профилем скорости газового потока в канале 1 посто нного сечени внутри него размещена гибка сетка 2. При воздействии на сетку 2 механизмом 4 измен етс степень кривизны сетки 2, что приводит к изменению профил скорости газового потока. 1 ил.In order to control the velocity profile of the gas flow, a flexible grid 2 is placed inside the channel 1 of a constant cross section. When the mechanism 4 is affected by the mechanism 4, the degree of curvature of the grid 2 changes, which leads to a change in the velocity profile of the gas flow. 1 il.
Description
Изобретение относитс к экспериментальной гидродинамике и предназначено дл формировани профил скорости газо- йых потоков.The invention relates to experimental hydrodynamics and is intended to form a velocity profile for gas flows.
Цель изобретени - управление профилем скорости газового потока.The purpose of the invention is to control the gas velocity profile.
На чертеже представлено устройство, разрез.The drawing shows the device section.
Устройство содержит канал 1 посто нного сечени с размещенной внутри него ;гибкой сеткой 2. Последн закреплена по периметру 3 внутри канала 1 и снабжена механизмом 4 дл перемещени центра 5 сетки 2 вдоль оси 6 канала 1.The device contains a channel 1 of a constant cross section with a flexible grid 2 placed inside it. The latter is fixed along the perimeter 3 inside channel 1 and is equipped with a mechanism 4 for moving the center 5 of the grid 2 along the axis 6 of channel 1.
При движении газового потока по каналу 1 управление профилем скорости потокаWhen the gas flow moves through channel 1, the flow velocity profile control

осуществл етс за счет изменени радиуса кривизны поверхности гибкой сетки 2. Изменени кривизны достигаетс воздействием на сетку 2 механизмом 4.This is accomplished by changing the radius of curvature of the surface of the flexible grid 2. The change in curvature is achieved by acting on the grid 2 by mechanism 4.
