流体力学实验论文

流体力学实验论文

写个论文才给20分？？？
算了，讲点吧
流体力学的主旨中心是围绕：流速越大压强越小，相反反之
相关机械有：飞机。喷雾器。。。。。。
利用性能较好，是纯天然的。。。呵呵
憋不出来了。。。没内容写了。。。。

针对生活中的物理现象进行实验的论证。500字论文

再给你些例子:
1、挂在壁墙上的石英钟，当电池的电能耗尽而停止走动时，其秒针往往停在刻度盘上“9”的位置。这是由于秒针在“9”位置处受到重力矩的阻碍作用最大。
2、有时自来水管在邻近的水龙头放水时，偶尔发生阵阵的响声。这是由于水从水龙头冲出时引起水管共振的缘故.
3、对着电视画面拍照，应关闭照相机闪光灯和室内照明灯，这样照出的照片画面更清晰。因为闪光灯和照明灯在电视屏上的反射光会干扰电视画面的透射光．
4、冰冻的猪肉在水中比在同温度的空气中解冻得快。烧烫的铁钉放入水中比在同温度的空气中冷却得快。装有滚烫的开水的杯子浸入水中比在同温度的空气中冷却得快。这些现象都表明：水的热传递性比空气好，
5、锅内盛有冷水时，锅底外表面附着的水滴在火焰上较长时间才能被烧干，且直到烧干也不沸腾，这是由于水滴、锅和锅内的水三者保持热传导，温度大致相同，只要锅内的水未沸腾，水滴也不会沸腾，水滴在火焰上靠蒸发而渐渐地被烧干，
6、走样的镜子，人距镜越远越走样．因为镜里的像是由镜后镀银面的反射形成的，镀银面不平或玻璃厚薄不均匀都会产生走样。走样的镜子，人距镜越远，由光放大原理，镀银面的反射光到达的位置偏离正常位置就越大，镜子就越走样．
7、天然气炉的喷气嘴侧面有几个与外界相通的小孔，但天然气不会从侧面小孔喷出， 只从喷口喷出.这是由于喷嘴处天然气的气流速度大，根据流体力学原理，流速大，压强小，气流表面压强小于侧面孔外的大气压强，所以天然气不会以喷管侧面小孔喷出。
8、将气球吹大后，用手捏住吹口，然后突然放手，气球内气流喷出，气球因反冲而运动。可以看见气球运动的路线曲折多变。这有两个原因：一是吹大的气球各处厚薄不均匀，张力不均匀，使气球放气时各处收缩不均匀而摆动，从而运动方向不断变化；二是气球在收缩过程中形状不断变化，因而在运动过程中气球表面处的气流速度也在不断变化，根据流体力学原理，流速大，压强小，所以气球表面处受空气的压力也在不断变化，气球因此而摆动，从而运动方向就不断变化。
9、吊扇在正常转动时悬挂点受的拉力比未转动时要小，转速越大，拉力减小越多．这是因为吊扇转动时空气对吊扇叶片有向上的反作用力．转速越大，此反作用力越大．
10、电炉“燃烧”是电能转化为内能，不需要氧气，氧气只能使电炉丝氧化而缩短其使用寿命。
11、从高处落下的薄纸片，即使无风，纸片下落的路线也曲折多变。这是由于纸片各部分凸凹不同，形状备异，因而在下落过程中，其表面各处的气流速度不同，根据流体力学原理，流速大，压强小，致使纸片上各处受空气作用力不均匀，且随纸片运动情况的变化而变化，所以纸片不断翻滚，曲折下落
