In fluid dynamics, inviscid flow is the flow of an inviscid fluid which is a fluid with zero viscosity. The Reynolds number of inviscid flow approaches infinity as the viscosity approaches zero. When viscous forces are neglected, such as the case of inviscid flow, the Navier–Stokes equation can be simplified to a form known as the … 展开
Ludwig Prandtl developed the modern concept of the boundary layer. His hypothesis establishes that for fluids of low viscosity, shear forces due … 展开
In a 1757 publication, Leonhard Euler described a set of equations governing inviscid flow:
展开• Couette flow
• Fluid dynamics
• Potential flow, a special case of inviscid flow
• Stokes flow, in which the viscous forces are much greater than inertial forces. 展开The Reynolds number (Re) is a dimensionless quantity that is commonly used in fluid dynamics and engineering. Originally described by 展开
Superfluid is the state of matter that exhibits frictionless flow, zero viscosity, also known as inviscid flow.
To date, helium is the only fluid to exhibit superfluidity that has been discovered. Helium-4 becomes a superfluid once it is cooled to below 2.2K, a … 展开CC-BY-SA 许可证中的维基百科文本 Euler equations (fluid dynamics) - Wikipedia
In fluid dynamics, the Euler equations are a set of partial differential equations governing adiabatic and inviscid flow. They are named after Leonhard Euler. In particular, they correspond to the Navier–Stokes equations with zero viscosity and zero thermal conductivity.
The Euler equations can be applied to incompressible and compressible flows. The incompressible Euler equations consist of Cauchy equations for conservation of mass and balance of momentu…Wikipedia · CC-BY-SA 许可下的文字- 预计阅读时间：10 分钟
Euler’s equation for inviscid fluid flow is a first-order, linear, homogeneous differential equation, arising from consideration of momentum conservation in a lossless / dissipationless …
