Boundary Layers and Fluid Layers
The presence of bodies and walls in a fluid flow results in the transfer of mass, momentum and heat, which occurs in addition to convection. These processesy sometimes develop next to the wall in a layer (called the “boundary layer”) which has a thickness that is much smaller than the characteristic size of the obstacle. The boundary layer can be either laminar or turbulent. Moreover, each transfer process can have its own particular boundary layer thickness. Chemical reactions can take place in the bulk of the fluid phase (in a flame for example) or at the wall (in heterogeneous reactions).
