Description

静态多级流体速度放大器
本发明可以不借助于可动的机械部件而使流体速度增大，因而本发明在许多应用领域具有优越性，特别是在流体速度是有限的情况下。
众所周知，速度为V的流体在冲击阻力系数Cr大于1的障碍物AB时，从尖缘A处(图2)开始流速增大。根据计算公式有：生成速度或脱离速度等于来流速度乘以物体阻力系数的平方根，即 V f = V a × C x
流体流过阻力系数为2.3的凹形半圆障碍物(图2)时，速度得以最大程度地增大，该阻力系数为已知阻力系数的最大值。
如果流速的增大能够重复进行，如同电子放大器，那么利用流体能量进行工作的装置，其性能或精确度将会有极大地提高。
具有上述廓形的障碍物横向放置在来流中，可以将其视为放大系数为 K = C x 的速度放大器，至少对与低压尾流区(abcde，图2)相邻的区域CE(图2)是如此。将另一障碍物(FG，图3)横向放置于加速后的流束(H1H2，图3)中，流体流过FG(图3)后流速进一步提高。为使流体速度得以进一步提高，障碍物FG必须放置在加速后的流束H1H2(图3)中，其宽度L2小于流束宽度(L1)，并且障碍物FG必须通过壁CF与障碍物CD相连接(图3)以使流体得以再次加速。二次加速后流体宽度的减小与加速后的流体速度成比例。
当流体流过依据上述位置和尺寸条件确定的每个新的障碍物时，流体速度的增加造成障碍物后部的低压Dp(图3)。根据阻力公式
阻力＝Cx×ρ×V2/2
Dp与来流速度Vf的平方及障碍物的阻力系数Cx成比例。
当流体速度增加导致流束的宽度e(图3)不足时，流束逐渐转变为无用的涡流。
以下是本发明的应用：
1)利用流体来工作的机器(T′)，在给定机器几何尺寸的条件下(图4)，流体速度的增加将极大地提高该机器的功率，例如空气动力涡轮。
2)如果将所说放大器障碍物演变成如连接在涡轮机(T)上的环状(剖面如图5所示)，加速后流体的流速将提供更大的动力。
3)如果将放大器障碍物M′、M″(图5)分别连接在主障碍物DC的两边，并且也呈圆环状，则在该组装装置后部的低压Dp，进而涡轮机(T)所产生的功率都将有更大的增加。
4)通过提高流体的真空度，使真空计和粘度计的灵敏度提高、结构坚固，因而极大地改善了上述仪器的使用(图6)。
5)气动力与液压动力的传送。提高流体在其路径末端处的流速，可以防止或部分补偿流速沿管道的压力损失，有利于测量、遥控和能量输送。
6)冲洗或钻孔枪利用纯净或加入填料的流体进行表面加工，流体的冲击力被增强了。
7)各种采矿和地下钻探用钻头。
应用举例：压缩空气冲洗枪。
借助具有用剖面形状符合前述要求的，如附图中DCFG所示厚金属箍结构，将具有矩形剖面PQRS(图7)的管子在其端部闭合。纯净空气流过两个半圆形障碍物后，流速增大

倍，也就是1.5的平方即2.3倍，气体冲击力增大2.3的平方倍，即5.29倍。
