.About Pangea Aerospace:We are a company dedicated to developing advanced propulsion systems for the space industry based on three key principles: high efficiency, sustainability, and reusability. We are revolutionizing the space industry with ground-breaking innovations that allow us to offer the best performance to cost propulsion systems.Our goal is to be the propulsion provider for the next generation of spacecraft, which are essential to meet the demands and compete in the booming space market of the next decade.We are a passionate, multicultural, and multidisciplinary team pushing the boundaries of what is possible in space propulsion technology.We have already made history by successfully testing the world's first 3D-printed Methalox Aerospike engine, marking a significant milestone for the space industry.We are looking for talented professionals to join our international team in Barcelona and Toulouse. We want to be a key player in improving diversity in the Aerospace sector as, in Pangea, we believe that diversity (gender, age, race, sexual orientation, beliefs, disability, culture, etc.) is a key to success. Within Pangea, everyone can grow with the same opportunities. We encourage you to apply. Individually we are different, but together we are an amazing team!We are looking for a CFD Engineer - Propulsion in Barcelona.About the job:We are seeking a highly skilled CFD Engineer specializing in Propulsion to join our Fluid Dynamics team in Barcelona. The successful candidate will leverage advanced CFD tools and techniques to model and optimize the engine's components, contributing to the design of ARCOS, PANGEA Aerospace ´s aerospike rocket engine. This role is crucial in enhancing engine performance, improving thermal efficiency, and ensuring structural integrity.Key Responsibilities:1. Multiphase Flow Simulation:- Simulate the behaviour of multiphase flows, particularly in fuel injection systems.- Model liquid fuel atomization, droplet formation, and spray dynamics during injection to optimize combustion efficiency.- Analyse the effects of fuel atomization on engine performance.2. Heat Transfer Analysis:- Perform detailed thermal analysis of rocket engine components, such as combustion chambers, nozzles, and cooling systems.- Model heat transfer mechanisms (conduction, convection, and radiation) to optimize the engine's components.- Integrate CFD analysis with Multiphysics phenomena, including fluid-structure interaction and thermodynamic effects, to assess temperature and pressure impacts on material behaviour.3. Optimization and Design Iteration:- Use CFD results to propose and refine design improvements, focusing on fuel injection systems, thermal performance, and thrust optimization.- Collaborate closely with the mechanical design and manufacturing teams to ensure that CFD-driven design modifications are implemented effectively
