  • Abstract:
  • The study of shockwave formation in nozzle designs is crucial for optimizing the performance and efficiency of propulsion systems. This research focuses on the comparative analysis of shockwave behavior in single bell nozzles under varying inlet pressures and Ambient pressure. By conducting a detailed computational study, the research aims to observe variations in shockwave formation and their impact on nozzle performance. The methodology involves using advanced computational fluid dynamics (CFD) simulations to analyses shockwave patterns and pressure distributions. The study highlights key performance metrics such as thrust, specific impulse, and flow separation behavior, providing a comprehensive understanding of how nozzle design responds to varying inlet and Ambient pressures. By understanding the nuances of shockwave formation and its effects, engineers can design nozzles that perform optimally across a range of operating conditions, enhancing the reliability and effectiveness of rocket and jet propulsion systems. Taguchi optimization is used to create a Design of Experiments (DOE) for conducting the simulations, and the results are validated using Analysis of Variance (ANOVA) and regression analysis. This approach ensures that the findings are robust and provides a regression equation for predicting nozzle performance under different conditions.
