Law of wall
WebThe Law of Laplace essentially states that the tension within the wall of a sphere filled to a particular pressure depends on the thickness of the sphere. Consequently, even at a constant pressure, the tension within a filled sphere can be decreased simply by increasing the thickness of the sphere's wall. http://brennen.caltech.edu/fluidbook/basicfluiddynamics/turbulence/lawofthewall.pdf

WebIn fluid dynamics, the law of the wall states that the average velocity of a turbulent flow at a certain point is proportional to the logarithm of the distance from that point to the "wall", or the boundary of the fluid region. This law of the wall was first published by Theodore von Kármán, in 1930. [1] It is only technically applicable to parts of the flow that are close to … Web壁面定律（law of the wall）是流体力学中的一个定律，指高雷诺数的湍流中某点平均速度与该点到壁面距离的对数成正比。该定律由西奥多·冯·卡门于1930年首先提出。 壁面定律仅在接近壁面但离壁面仍有一小段距离的部分区域适用（最贴近壁面的区域则为粘性力主导）。其表达式为：Schlichting & Gersten ...
