The no-slip boundary condition is a fundamental concept in fluid mechanics stating that the velocity of a fluid in contact with a solid boundary is equal to the velocity of that boundary itself. This means that at the surface of the boundary, the fluid sticks to it, leading to zero relative motion between the fluid and the surface. This condition is crucial for accurately modeling fluid flow in simulations, especially in Computational Fluid Dynamics (CFD) applications in chemical engineering, where understanding flow behavior at boundaries is essential for predicting system performance.
congrats on reading the definition of no-slip boundary condition. now let's actually learn it.
