Significance of navier stokes equation
Webwhere \(u\) is the (vector-valued) fluid velocity, \(p\) is the pressure, \(\mu\) is the viscosity and \(f\) is a (vector-valued) external force applied to the fluid. This model gives the motion of a fluid in the high viscosity limit and has applications in industrial, geological and biological flows. For less viscous fluids we use the Navier-Stokes equation which … WebAdd a comment. 1. Answering (1) requires understanding what the Navier-Stokes equations represent and how they are derived. The Wikipedia article for the Navier-Stokes equations shows this derivation from the Cauchy momentum equation for continua, in which pressure shows up explicitly. The Navier-Stokes equations thus have this built into them ...
