8.- 流体力学

流体力学分支研究流体在静止(流体静态)或在运动(流体动​​力学)中的行为定律及其与固体的相互作用过程。能够流动(即移动)的物质被视为流体。其中包括液体(水,油,酒精,牛奶,硫酸,汽油)和气体(空气,氧气,氮气,氦气,氩气,甲烷,丁烷,天然气)。

从我们周围的空气,游泳池中的水到灌溉用水,使我们能够在汽车中制动的液压系统,供暖或空调,以及在我们自己的血液系统中流体研究基于著名的阿基米德原理和帕斯卡原理,伯努利方程,文丘里效应或达西定律等。寻求适用性的流体机械工程领域是通过经验和数学方法研究的,重点介绍了无量纲数,例如雷诺兹,普兰特,马赫和弗洛德。流体力学原理的超越性使发明保持了它们的共同点:通过通道的水输送,海上和空中运输,液压,热力和气动机器,管道中的解决气蚀问题或冲击的解决方案。柱塞,液压和气动传动及控制装置等。

考虑到流体在各种应用中的相关性,了解流体的性质(即流体的类型)并根据其特性进行描述非常重要。最重要的是:压力,温度,体积,密度,粘度,可压缩性,比热,热膨胀性和混溶性。

8.1.- 流体力学模块化实验室

液压学是研究流体力学性质的科学分支,流体力学是液压学的基础。EDIBON旨在以简单、实用的方式回应学术界对流体力学基础教学和学习的需求。为此,它提供了一种灵活且模块化的系统,用于学习基础流体力学。通过所提出的模块系列,学生进行实验,清晰展示液压学定律。通过这些实验,学生自然、愉快且毫不费力地获得了使用液压仪器和工具的经验。流体力学实验室中的设备能够进行流体特性研究、流量测量与控制,研究控制流体力学的主要现象和原理,并了解广泛应用于工业的设备。

8.2.- 度量衡

计量学是研究量的测量的科学。它的基础是力求在参考值与需要定量的对象或现象之间建立起关系,并获得测量的表达式。测量必须是可重复的,而且不确定度尽可能小,误差取决于技术人员的专业知识或所用仪器的精度。在测量中获得的数值是为了以标准化的方式在单位系统中表示,例如国际系统。需要测量的领域很广,从社会科学、健康科学到最纯粹、最实验的科学都有。目前,在创新和优化测量仪器及其校准方面取得了进展。我们都曾在某些时候做过一些测量,比如车辆轮胎的胎压,或者玩游戏所需的时间。有很多设备可以让我们测量基本量级。例如,可以用转子流量计或流量传感器测量流体的流量,用布顿压力计测量流体循环的压力,用热电偶测量流体的温度等。

8.3.- 静水压

流体静力学是流体力学的一个分支,研究流体在容器中,没有力改变液体的静止状态或运动状态时的行为和相关现象。相反,流体力学研究的是运动中的流体。流体静力学是基于帕斯卡原理和阿基米德原理。帕斯卡原理指出:"在容器中密闭的流体中,压力以相等的强度向各个方向传递"。同样,阿基米德原理也指出:"当一个物体浸入液体中时,它对该物体施加的向上的力等于它所脱落的液体的重量"。从这些原理出发,定义了流体静力学的基本方程。 Dp = ρ g...

8.4.- 流可视化

流体的流动被框定在流体力学的分支中。研究的重点是流体运动的压缩,条件是牛顿定律和质量与能量守恒,以及斯托克斯、雷诺或普朗特数等定律。通过流体的运动和方向的可视化,借助于电流和流线,可以了解压力和速度的分布。电流线总是显示与速度平行,而流线是流体的路径,这两种线型在静止状态下是一致的。流体可以被认为是可压缩的(气体)或不可压缩的(液体)。这些流体根据其性质和所受的力,在管道、通道、涡轮机等内可能呈现层流或紊流。当流体呈现出缓慢而有序的运动,流体的片面平行而平稳地滑动时,就会出现层流。而在湍流中,运动的能量比较大,不规则,不可预测。如今,流体的流动是一个重要的领域,因为它对工业设备的尺寸、民...

8.5.- 液压通道

水是生物所使用的基本元素,自古以来,为了分配和消耗水,人们开发出了不同的巧计,如渠道。水力或明渠,或简称渠,是指向大气开放的输送流体的管道,它在其中因自身重量和施工坡度而发生位移。渠道可以是天然的建筑(河流或溪流),也可以是人工的,即使是部分填埋的管道也被认为是渠道。渠道的建设可以是不同的几何形状,并以不同的流态(永久均匀流或非均匀流)和排流态(亚临界、临界或超临界)运行。渠道的主要参数有:吃水或深度、断面顶宽、底板、湿润周长和渠道坡度。此外,还设计了许多类型的控制结构,用于流量调节和排放测量,如堰/围堰(薄壁或厚壁和虹吸器)或闸门,可以有不同的几何形状。渠道在工程中起着重要的作用,从广...

8.6.- 空气动力学

空气动力学是流体力学的一部分,研究运动中的气体和其中的物体所受的力或反应。对于空气动力学的重要性,我们必须加上它对航空学的贡献价值。根据马赫数或机动车相对于空气的相对速度,空气动力学根据这个数字比单位低或高,分为亚音速和超音速。在流体力学中,在研究气体的范围内,通常使用空气,通常量化的主要变量是速度、压力、阻力或升力等。用于流体力学试验的风洞被广泛用于确定风对不同类型物体的作用。待研究的模型保持静止状态,而流动介质则处于运动状态。风洞的主要部件有:风机、扩散器、室、收缩器和试验段。每当我们移动或投掷一个物体时,都会有一些我们平时没有注意到的物理原理发生作用。了解空气动力学的原理,在很多活...

8.7.- 流体机械

在流体力学中,一个特殊的应用领域是流体机械的研究。流体机是将通过的流体的能量转化或将能量传递给流体的设备。这种液体可以是气体、蒸汽或液体。根据这个定义,可以推导出以下分类:发电机。涡轮机:由于通过它们的流体运动量的变化,在轴上产生扭矩和动力。风力发电机:将风的动能转化为机械能。l消耗机。...

8.8.- 流体管道系统

在工程中,流体管线被定义为能够将流体从源头输送到所需目的地的结构或工作。有两种类型的传导:封闭的(管道、隧道或下水道)和开放的(自然流)。封闭管道中的流量一般会受到压力,不像那些自由表面的管道。管道在工程中的应用是多种多样的,所以要对其进行调整。为此,它们有部件,在导水管道中主要是管道和部件(接头、弯头、异径管、阀门等)。此外,根据设计规格或工作要求,管道可以通过泵系统、重力或两种机制输送流体。同时,由于材料中可能存在较厚的固体或流体的磨蚀性等特性,因此研究材料很重要。最明显的例子是在饮用水的分配和供应网络中发现的管道。人类的用水设施,必须保证安全和卫生,它是由水箱、管道、配件等各种要素...

当今社会的需求对任何行业来说都是一种挑战,因为行业必须在不断的发展和改造中才能适应这些需求。近年来,由于新的工业革命或 "工业4.0","工业物联网"(IIoT)和 "智能工厂...
