Conference paper


A new technique for visualization and quantification of local heat and mass transfer is presented. The technique is based on chemisorption of dyes at solid surfaces. The intensity and the distribution of the colour is directly correlated to the transferred mass. With a remission photometer the test samples are evaluated. First results with this new technique are presented for mass transfer in multiple-jet-stagnation flow.
