The Casimir-Lifshitz interaction emerging from the relative movement of layers in stratified dielectric media (e.g., nonuniformly moving fluids) is considered. It is shown that such movement may result in a repulsive Casimir-Lifshitz force exerted on the layers, with the simplest possible structure consisting of three adjacent layers of the same dielectric medium at zero temperature, where the middle one is stationary and the other two are sliding along a direction parallel to the interfaces of the layers.
