Boundary layer theory mass transfer
WebVelocity and Concentration Boundary Layers for Laminar Horizontal Flow Across a Flat Plate = thickness (height) of the velocity boundary layer (length) = thickness (height) of the concentration boundary layer (length) = fluid viscosity (pressure time) or (mass length-1 time-1) = fluid density (mass volume-1) WebMean Velocity Profiles - Turbulent Boundary Layers: Near a solid boundary the flow has a distinct structure, called a boundary layer. The most important aspect of a boundary layer is that the velocity of the fluid goes to zero at the boundary. This is called the "no-slip" condition, i.e. the fluid velocity matches (has no slip relative to) the ...

In physics and fluid mechanics, a boundary layer is the thin layer of fluid in the immediate vicinity of a bounding surface formed by the fluid flowing along the surface. The fluid's interaction with the wall induces a no-slip boundary condition (zero velocity at the wall). The flow velocity then monotonically … See more Laminar boundary layers can be loosely classified according to their structure and the circumstances under which they are created.
