This article examines unsteady flows of rheologically complex fluids in a flat channel using the Oldroyd-B model after the actuator is switched off. It is assumed that until the actuator is switched off, the fluid flow is steady under a constant pressure gradient. From a given point in time, the pressure gradient in the system is assumed to be zero. The problem is solved analytically using the Laplace transform. Based on the solutions obtained, the corresponding hydrodynamic regularities are determined, which are important for technical and technological processes.
