Example 7.2: The fundamental solution of the Stokes equations in three dimensions corresponds to a point force Fδ(x) on the right of the momentum equation, F a constant vector: ∇p − μ∇2u = …
One of the fundamental results in low Reynolds hydrodynamics is the Stokes solution for steady flow past a small sphere. The apllicatiuon range widely form the determination of
- Consider the point P located in the fluid element at time t undergoing a uniform flow v(x, y,z,t) , which means that all spatial derivatives of the components of the velocity are zero. The fluid element will simply translate in the direction of the velocity and not undergo any change in shape.
Stokes flow, or “slow viscous flow”, describes fluid dynamics at low Mach number and low Reynolds number. In Kinetic Theory we derived the compressible Navier–Stokes–Fourier …

Oseen Flow. In an effort to extend the Stokes flow solutions around finite objects to finite Reynolds numbers, Oseen (1910) suggested modifying the inertial terms in the Navier-Stokes …
Three features of this Stokes flow field. Slow decay of disturbance fields away from the translating sphere, as r−2 for the pressure and as r−1 for the dominant portion of the velocity. …
