The No-Slip Boundary Condition in Fluid Mechanics

WebIn fluid dynamics, it is usually the pressure or velocity values that are imposed on the boundary of the domain. For instance, when solving fluid dynamics problems for a viscous fluid with no-slip and no-penetration conditions, according to the Dirichlet boundary condition, the component of velocity should be zero at the boundary.

WebThe no-slip boundary condition for the Navier–Stokes equations is replaced by the no-penetration condition: There is no fluid passing through solid boundaries. A naive expectation is that the limit of a family of solutions of the Navier–Stokes equations, as the Reynolds number increases without bound, is a solution of Euler’s equations. WebMar 5, 2024 · In fluid dynamics, such a block of fluid is said to be a “free body”. Because the flow is assumed to be steady and uniform, all of the forces in the streamwise direction that are exerted upon the fluid within the free body at any given time must add up to be to zero. ... By the no-slip condition, the velocity is zero at \(y = 0\), so the ...
