The “static temperature at the throat where the flow is sonic,” denoted as Tt, refers to the temperature of the fluid at the narrowest cross-sectional area of a nozzle or flow passage where the flow velocity has reached the speed of sound. This condition is often referred to as “sonic flow” or “choked flow.”
- Static temperature at the throat (Tt) in N/m^2
- Inlet Temperature (T0) in N/m^2
- Ratio of static temperature at sonic flow to the inlet temperature (T*/T0)
