Descripció:

Rocket nozzles play a critical role in propulsion systems, efficiently converting high-pressure, high-temperature exhaust gases into thrust. The flow field within these nozzles is characterized by complex phenomena, including shockwave interactions, boundary layer effects, and turbulent mixing, all of which influence performance and efficiency. These challenges are further amplified in advanced nozzle designs, for instance in the aerospike nozzle, where the absence of a fixed exit geometry introduces additional intricacies in flow behavior. Understanding these phenomena is essential for optimizing nozzle performance and developing more efficient propulsion systems. Accurate numerical simulations are key to addressing these challenges, providing insights into the behavior of the flow field and enabling the prediction of critical performance parameters. However, reliable simulation tools are essential to ensure that the results accurately capture the physical phenomena involved. This project aims to contribute to this understanding by first simulating a parabolic nozzle, which will serve as a validation case for the computational framework. This step ensures that the numerical setup is robust and capable of producing dependable results. Building on this foundation, the project will focus on analysing the flow field of different nozzle geometries to understand their effect on the flow field and performance of a rocket propulsor. Computational Fluid Dynamics (CFD) will be used, providing a deeper understanding of key aspects such as flow expansion, velocity field, and pressure distributions. By engaging with this project, students will not only develop valuable skills in CFD but also contribute to advancing the understanding of an innovative propulsion technology.
