Sažetak
The design of supersonic E-D nozzles is crucial for enhancing the performance of jet engines in supersonic aircraft by increasing thrust and improving overall efficiency. The aim of this study is to develop an E-D nozzle design and to investigate the influence of the central body radius on the flow characteristics and efficiency of the nozzle. The results show that increasing the radius of the central body leads to a reduction in nozzle length, wall surface area and thrust. The ANSYS-Fluent software was used to compare an E-D nozzle and a TIC nozzle with the same surface area ratio. The results of the study show that the E-D nozzle is smaller in size than the TIC nozzle with the same cross-sectional area ratio. For over-expanded flow conditions, the flow adheres to the walls of the E-D nozzle, while it detaches from the walls of the TIC nozzle. In addition, the E-D nozzle delivers a significantly higher thrust than the TIC nozzle, with an estimated increase rate of 12.97 %.
