Abstract
The chemical plotting of boundary layer flows in liquids with the use of uncompacted, coated, anodically oxidized aluminum surfaces is effected using a colored or uncolored liquid or a coating or pointillization with a substance, preferably a dye, soluble in water or organic media and which can be included or adsorbed in the eloxal layer. The process serves to plot boundary layer flows in water, organic media and oils in a wide temperature range.
