| Число Фруда |  |
Число́ Фру́да, или критерий Фруда, — один из безразмерных критериев подобия движения жидкостей и газов. Применяется в случаях, когда существенно воздействие внешних сил. Введено Уильямом Фрудом в 1870 году. Википедия
For Fr < 1 the flow is called a subcritical flow, further for Fr > 1 the flow is characterised as supercritical flow. Origins · Other applications · Extended Froude number |
Froude number (Fr), in hydrology and fluid mechanics, dimensionless quantity used to indicate the influence of gravity on fluid motion. |
The Froude number is a measurement of bulk flow characteristics such as waves, sand bedforms, flow/depth interactions at a cross section or between boulders. |
The Froude number is defined as a dimensionless number that is proportional to the square root of the ratio of inertial forces to the weight of fluid. |
When Froude No. is at a critical point that is Fr = 1, then the velocity of the flow is equal to the velocity of surface waves, which is also known as the ... |
A Froude number of 1 defines critical mean depth vs. critical velocity. Hydraulic Mean Depth. Hydraulic mean depth can be calculated as. hm = A / T (2). where. |
30 мар. 2024 г. · ... Froude number. For U/(Nh) >> 1, the flow ascends over the obstacle with no upstream deceleration. For U/(Nh) << 1, a region of upstream flow ... |
26 сент. 2023 г. · The Froude number is a dimensionless ratio that quantifies the relative importance of inertial forces to gravitational forces in a fluid flow. |
