Hydrodynamic control of the growth of the two dimensional boundary layers around a flat plate placed in the center of convergent: concept of uniform accessibility from the point of view of the diffusion matter

摘要

The authors indicated numerically, that a plane surface placed in the center of convergent and crossed by a Newtonian fluid, in laminar and permanent flow is uniformly accessible from certain distance of the entering edge when the velocity at the outer boundary of the boundary layer that develops on its increases linearly with the longitudinal component ... They explained the concept of hydrodynamic and mass uniform accessibility and set its validity area according to the Reynolds number. Such study can assist in the understanding of vapor phase deposition phenomena of semiconductors.
