Low-temperature plasma jets are used to treat both the motionless and moving objects (targets or substrates). The gas-dynamic aspects of the plasma jet’s interaction with the target are important and have to be taken into account in selecting the most efficient plasma processing parameters. Clearly, the spreading of plasma jet over a fast-moving surface is significantly different from its spreading over a fixed target. This question is investigated by the example of the interaction of an air plasma jet with a surface of fast-rotating dielectric disk. It is shown the change in the shape of the jet striking perpendicularly the moving substrate happens due to the movement of a thin layer of the ambient air adjacent to the fast-moving surface. This effect can have a noticeable influence on the reactive particles transfer from the plasma jet onto the surface to be treated.
