Numerical Thermal Analysis of Jet-Film Cooling over a GasTurbine End-wall

In my recent computational study, I delved into the intricate dynamics of film cooling in gas turbines, a critical aspect of aerospace engineering. This project was inspired by the foundational experiment conducted by Atul Kohli and David Bogard, focusing on the effectiveness of film cooling jets under varying conditions of mainstream turbulence. My core objective was to develop a comprehensive understanding of how these cooling jets interact within highly turbulent environments, a scenario often encountered in advanced propulsion systems. Utilizing my skills in computational fluid dynamics (CFD), I meticulously analyzed the fluid flow and thermal properties of these cooling jets.

The study involved a detailed assessment of different turbulence models, specifically comparing anisotropic and isotropic approaches, to determine their performance and accuracy in simulating real-world conditions. I employed three distinct models – the Reynolds Stress Model (RSM), k − ω SST, and k – ω BSL – to analyze the normalized mean temperature along both longitudinal and lateral cross-sections of the jet centerline. This approach allowed for a nuanced understanding of temperature distribution and jet behavior in various turbulent intensities. The findings from this study not only provided insights into the most effective turbulence models for predicting film cooling effectiveness but also highlighted the limitations of current modeling techniques. This work, a part of my broader exploration in aerospace engineering, underscores my commitment to advancing our understanding of thermal management in high-performance systems.
