Description

Г Изобретение относитс  к экспериментальному гидродинамическому обО рудованию. Известны гидродинаиическиб трубы ,имеющие закрытые(ограниченные жесткими -стенками) или открытые (вода вытекает струей в атмосферу) рабочие части,Основным недостатком закрытой час2и  вл етс  стеснение потока, вызванное тем, что  шдкость ограничена стенками, форма которых не совпадает с мни ми тока течени  в безг.раничной ашдкости. В гидротрубе с открытой рабочей частью не происходит стеснени  течени . Однако вли ние весомости жидкости приводит к изменению скорости течени  в рабочей части вдоль потока. При этом в гид ротруба с горизонтальным течением скорость мен етс  по направлению, а при вертикальном течении измен етс  величина скорости, Изменеj пие скорости происходит из-за то1 .ГО, что атмосферное давление не B СОСТОЯНИИ компенсировать гидростатическое давление в жидкости. Целью изобретени   вл етс  компенсаци  гидростатического давлени  воды, движущейс  -в рабочей части трубы. Достигаетс  это тем, что труба выполнена с эластичной вставкой , размещенной с зазором в кожухе , образующем емкость, сообшаю цувэс  с труоой посредством ооразовашшх в ней отверстий. На чертеже показана предложенна  гидродинамическа  труба. Она содержит жесткие стенки I, эластичную вставку 2 и кожух 3, образущие заполненную водой емкость 4, котора  сообщаетс  через отверсти  5 в стенках с потоком 6 воды в гидротрубе. Эластична  вставка размещаетс  с зазором относительно кожуха, На поток воды в гидротоубе со стороны воды, ваполн щеи емкость , через эластичную вставкуThe invention relates to experimental hydrodynamic equipment. Hydrodynamic pipes with closed (limited by rigid walls) or open (water flows into the atmosphere) working parts are known. The main drawback of the closed part is flow restriction caused by the fact that the discharge is limited by walls whose shape does not coincide with the views of the current flow in bezg.ranichnoy Ashdkost. In a hydraulic pipe with an open working part, the flow is not constrained. However, the influence of the weight of the fluid leads to a change in the flow velocity in the working section along the flow. In this case, in a horizontal flow hydrotube, the velocity changes in direction, and in vertical flow, the magnitude of the velocity changes. The velocity change is due to the fact that the atmospheric pressure does not compensate for the hydrostatic pressure in the fluid. The aim of the invention is to compensate for the hydrostatic pressure of the water moving in the working section of the pipe. This is achieved by the fact that the pipe is made with an elastic insert, placed with a gap in the casing, forming a container, communicating with the pipe through the holes through the holes in it. The drawing shows the proposed hydrodynamic tube. It contains rigid walls I, an elastic insert 2 and a casing 3 forming a container 4 filled with water, which communicates through the holes 5 in the walls with a stream 6 of water in the hydrotube. The elastic insert is placed with a gap relative to the casing. To the flow of water in the hydrotub from the water side, to fill the tank, through the elastic insert.
