ABSTRACT:
Process and appliance for conveying liquid or gaseous fluids, this process involving no mechanically movable propelling elements, but rather the formation, on the fluid that is to be conveyed, of interfaces with an additional fluid, and the application of a tension gradient at these interfaces, so that the so-called Marangoni effect is utilized for propelling the conveying stream.
