Tīmeklis2024. gada 1. febr. · An optimum nozzle geometry is one where choked flow is achieved at a larger critical pressure ratio value when compared to other nozzle geometries. This is associated with a higher pressure recovery as the fluid exits the throat of the nozzle and travels through the divergent section, minimizing pressure … TīmeklisThe Optimum Expansion Ratio is the reciprocal of this value 𝐴𝑒 𝐴∗ = 1 0.1066 =9.37 Note that these ratios are dimensionless. The nozzle cone exit diameter (De) can now be calculated. Cross-sectional area is related to diameter by the following relationship 𝐴= 𝜋 4 𝐷2 Since D*= 10mm, 𝐴∗= 𝜋 4 (10)2=78.5𝑚𝑚2
