Tīmeklis2024. gada 11. aug. · The length of the nozzle, nozzle entrance arc angle, and inner trailing edge gradient (θ d) seem to play a major in determining the objective function. Figure 5 represents the comparison of the design variables and objective function for the baseline and optimum geometry. The optimum and baseline nozzle contours are … 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 …
