The results of the study of the flow formation and its dynamics in the plasma focus discharge on the PF-3 facility using the streak camera are presented. To study the propagation of the flow in the background plasma and its structure, the facility has a three-section flight chamber. A comparison of the optical streaks obtained in the pinching region with the images obtained using frame cameras shows that at the final stage of pinching, a bright object can be observed over the current sheath, which we associate with the incipient flow. Measurements in the flight chamber showed that the flow has a complex structure, possibly related to the development of instabilities. When an external poloidal magnetic field is applied, the flow becomes more compact and the radiation intensity of the flow increases.
