A CD Nozzle is a type of variable area passage designed to accelerate gases to supersonic speeds. It features a converging section where the minimum area is located at a specific point known as the throat. This study presents a comparative flow analysis conducted at various divergent angles, executed in two distinct phases. The first phase involved the design of the convergent-divergent nozzle and the subsequent computational fluid dynamics (CFD) analysis. The second phase entailed a comparison with another foundational study. For the analysis, a two-dimensional axisymmetric nozzle geometry was created using Ansys DesignModeler, and the CFD analysis was performed with Ansys Fluent. The primary distinction between the two geometries lies in the outlet divergence angle, while all other dimensions, including the sectional area, throat cross-sectional area and nozzle length, were maintained constant. The outlet divergence angles examined were 10°, 15° and 20°. The analysis considered the velocity, pressure and temperature profiles for both configurations. The simulations indicate that a larger outlet divergence angle correlates with a higher speed magnitude. Notably, the nozzle with a 20° divergence angle demonstrates a lower temperature and pressure distribution throughout the expansion zone when compared to the 10° and 15° nozzles, which exhibit elevated temperatures and pressures in the same region. Given that the 20° nozzle achieves a higher exit velocity, it appears to be the most advantageous option based on the current findings.
