Description

Изобретение относитс  к прикладной аэрогидродинамике и может быть использовано дл  исследований течений жидкости и газа.The invention relates to applied aerohydrodynamics and can be used to study the flow of liquid and gas.

Цель изобретени  - повьш1ение эффективности за счет измерени  частоты колебаний струны, помещенной в поток перпендикул рно ему.The purpose of the invention is to increase the efficiency by measuring the oscillation frequency of a string placed in a stream perpendicular to it.

Способ реализуетс  следующим образом .The method is implemented as follows.

В поток жидкости или газа (или газа и жидкости, возможно с примес - ми) внос т струну, располага  ее так, чтобы была перпендикул рна направлению набегающего потока. Перемеща  струну в пространстве, измер ют (например , стробоскопическим методом) .частоту колебаний струны при размещении ее в различных точках с известными координатами. По полученным координатам точек измерени  и соответствующим частотам колебаний струны в каждой точке воспроизвод т картину течени . Необходима  точность измерений достигаетс  лишь при условии, если частота изменени  скорости течени  в потоке меньше собственной частоты струны.The string is introduced into the stream of liquid or gas (or gas and liquid, possibly with impurities), so that it is perpendicular to the direction of the incident flow. By moving the string in space, the frequency of oscillation of the string when placed at various points with known coordinates is measured (for example, by the stroboscopic method). The obtained measurement point coordinates and the corresponding vibration frequencies of the string at each point reproduce the flow pattern. The required measurement accuracy is achieved only if the frequency of the flow velocity in the stream is less than the natural frequency of the string.
