WebFeb 1, 2015 · The results with the pseudo free-slip condition are also given for comparison. In the case of a no-slip particle without rotation, i.e. ω x = 0, the analytical value of C D = 24 is fairly well reproduced. With rotation, the drag increases to C D = 31.29 and the torque is M T = 1.05. With the pseudo-free slip condition, Eq.

WebDefine no slip condition. applied to fluids. This means that the particles that are in direct contract with the surface the fluid flows on (or under) do not move (they do not slip against that surface). You can think of this as a very thin layer of fluid particles that do not move. The particles on top of this thin layer move. Let’s go back to the syrup example.

WebFeb 14, 2024 · The Robin boundary condition is a type of boundary condition named after Victor Gustave Robin (1855–1897).
