Abstract

Изобретение относитс  к экспериментальной гидродинамике, а именно к способам изучени  динамических характеристик моделей транспортных средств. Цель изобретени  - расширение функциональных возможностей. Способ включает размещение исследуемого тела 2 в рабочем участке 1 гидротрубы, подачу в ее контур сжиженной углекислоты при статическом давлении в рабочем участке 1 выше давлени  упругости паров при температуре испытани  и ее последующую циркул цию. Количество фаз в потоке регулируют путем снижени  давлени  в контуре трубы ниже давлени  упругости паров при отсутствии циркул ции. Фиксируют наличие и количество газовой фазы в потоке жидкой углекислоты, после чего осуществл ют циркул цию. Визуализацию пол  давлени  в рабочем участке производ т путем изменени  давлени  в контуре трубы при циркул ции рабочей жидкости, фиксиру  давление, при котором в местах пониженного давлени  образуютс  пузырьки газа, и точки потока, где происходит это образование пузырьков. 4 ил.The invention relates to experimental fluid dynamics, in particular to methods for studying the dynamic characteristics of vehicle models. The purpose of the invention is to expand the functionality. The method includes placing the test body 2 in the working section 1 of the hydraulic pipe, feeding liquefied carbon dioxide into its circuit at a static pressure in working area 1 higher than the vapor pressure at the test temperature and its subsequent circulation. The number of phases in the flow is controlled by reducing the pressure in the pipe loop below the vapor pressure in the absence of circulation. The presence and amount of a gas phase in a stream of liquid carbon dioxide is recorded, and then circulated. The visualization of the pressure field in the working section is carried out by changing the pressure in the pipe contour during the circulation of the working fluid, fixing the pressure at which gas bubbles form at the low pressure points, and the flow point where this formation of bubbles occurs. 4 il.
