discuss how boundary layer form outside the cell and how it can be impede further diffusion ? (200word )
Answers
Answer: hey mate here's your answer
Explanation: boundary layer develops because of diffusion of zero momentum at the wall to the top.and the increase in the boundary layer thickness is infinite domain on the top The viscous nature of airflow reduces the local velocities on a surface and is responsible for skin friction. The layer of air over the wing's surface that is slowed down or stopped by viscosity, is the boundary layer. There are two different types of boundary layer flow: laminar and turbulent.When a fluid rotates and viscous forces are balanced by the Coriolis effect (rather than convective inertia), an Ekman layer forms. In the theory of heat transfer, a thermal boundary layer occurs. A surface can have multiple types of boundary layer simultaneously.
