Hi, I am Rajkumar Sampathkumar, a double masters graduate specialized in computational fluid dynamics. The fascinating field of fluid dynamics have significantly shaped the research into aerospace, automotive and other industries. My academic background and hands-on experience in CFD modeling and simulation equip me with the expertise to analyze and solve complex fluid flow problems in diverse industries. I have a strong foundation in numerical methods, turbulence modeling, and fluid-structure interaction, coupled with proficiency in industry-standard CFD software like ANSYS Fluent, Star-CCM+ and OpenFOAM. During my group design project, I worked in a team of 5 to design and optimize a heat exchanger for preheating liquid hydrogen fuel for combustion in aerospace applications. The heat exchanger was modelled in SOLIDWORKS and simulated in Ansys Fluent. The results showed that the liquid hydrogen fuel was preheated effectively to reach the critical temperature, optimal combustion in a turbine or turbofan type aircraft engines. I was able to modify an existing heat-exchanger model to improve the preheating process.During my individual research project, I focused on aerodynamic shape optimization of a hypersonic waverider using an adjoint-based method in Star-CCM+. The project successfully improved the waverider’s aerodynamic efficiency and lowered the surface temperatures, demonstrating the potential for optimization techniques to enhance performance in high-speed aerospace applications. Passionate about applying CFD to optimize designs, enhance efficiency, and contribute to innovative engineering solutions, I am continually seeking opportunities to collaborate on challenging projects that push the boundaries of fluid dynamics in sectors such as aerospace, automotive, energy, and environmental engineering.
