Laminar-turbulent transition and its effects on heat transfer in rotating flowsHis PhD research focuses on laminar–turbulent transition in rotating flows and its influence on heat transfer in engineering systems. In particular, he investigates flow behaviour inside high-pressure compressor (HPC) cavities in Gas turbines, where rotating-disc boundary layers strongly affect thermal performance and component life. A key part of the research examines the transition of Ekman boundary layers, identifying the instabilities that trigger turbulence and alter heat-transfer rates. Direct Numerical Simulation (DNS) is used to resolve the detailed transition physics under conditions relevant to turbomachinery operation. The work also explores passive control strategies such as grooves and ribs to modify turbulence development and improve thermal management. Overall, the research contributes to better predictive tools and more efficient cooling design for rotating compressor systems.
