Résumé

The results of the experimental study of unsteady-state mass transfer on a surface of bodies of various configuration (a flat plate, a cylinder, a sphere) immersed in an external fluid flow and also on a surface of a flat channel are given in this report. The tests were carried out in the region of small Fo numbers and large Pr numbers. Measurement of local and total mass transfer was made by the electrochemical method of limiting current. Unsteadiness was caused by stepwise change of concentration on a wall. The experimental data according to a flat plate and flat channel are agreeded with available theoretical solutions.
