Local Mass Transfer Coefficients at Walls Impinged by Unsubmerged Multijets Issued from Very Porous Distributors

The paper deals with the experimental determination of the spatial distribution of local mass transfer coefficients at a solid surface receiving unsubmerged liquid multijets issued from several categories of distributors. The experimental technique uses microelectrodes imbedded in the solid surface and allows the local mass transfer coefficients and the local shear stress to be determined at the same places
