Abstract
The endeavors to develop a specialized design tool tailored for analyzing the viscous flows encountered by re-entry vehicles during their return to Earth's atmosphere. Given the extreme speeds and temperatures involved, effective thermal management is paramount to ensuring the safety and structural integrity of these vehicles. Computational fluid dynamics (CFD) simulations offer a powerful means to explore the intricate dynamics of viscous interactions, accurately modeling airflow and accounting for parameters such as viscosity, turbulence, and heat transfer. In this investigation, the focus lies on improving heat distribution near the heat shield of a re-entry vehicle module through the incorporation of fins into the vehicle's structure. By employing the axisymmetric Navier-Stokes equations and the k-epsilon turbulence model, this study aims to deepen our understanding of viscous flows in re-entry vehicles and the efficacy of heat dissipation strategies, such as fin configurations.
