The height of the nozzle throat, denoted as “h*,” refers to the vertical distance from the nozzle’s centerline to a specific point within the nozzle where the cross-sectional area is at its minimum. In other words, it is the height measurement perpendicular to the nozzle’s centerline at the narrowest point of the nozzle, known as the throat.Â
- Height of the nozzle exit (he) in m
- Ratio of area at the nozzle exit to the nozzle throat area (Ae/A*)
- Height of the nozzle throat (h*) in m
