Convergent Nozzle Behavior

This lecture focuses on the behavior of a convergent nozzle, discussing the impact of varying back pressure on flow characteristics. It explains how changes in back pressure affect flow speed and pressure distribution along the nozzle, leading to different flow regimes. The lecture covers the concept of sonic blockage, where the flow reaches a maximum value and cannot be further increased by reducing back pressure. It also introduces the use of expansion waves to transition from high to low pressure regions. The analysis includes graphical representations of flow parameters at different points along the nozzle, illustrating how flow properties evolve from the reservoir to the nozzle exit. The lecture concludes by hinting at the upcoming study of convergent-divergent nozzles, which present more complex flow phenomena.
