WebConverging supersonic flow: ∂As< 0 and M >1 Equation (16.17a). Here, ∂Asis still < 0, but now M >1. Then, Eq (16.17a)tells us that ∂psmust be > 0 and the pressure increases in the direction of flow. Equation (16.17b). If ∂As< 0 and M >1, then Eq. (16.17b)tells us that ∂Vsmust be < 0, or the flow velocity must decrease in the direction of flow.

"WebAs previously mentioned, in order for a flow to become supersonic, it must pass through a duct with a minimum area, or sonic throat. Additionally, an overall pressure ratio, P b /P t, of approximately 2 is needed to attain Mach 1. Once it has reached Mach 1, the flow at the throat is said to be choked.
