Research project: An Investigation Into Transonic Flows Over High-Pressure Gas Turbine Blade Tip

Abstract

The aviation industry remains to this date still a high polluter, thus requiring continuous improvement targeting fuel burn due to its adverse impact on the environment and economy. A minimal reduction of 0.5% could save an airliner over £77m annually and increase the part life cycle (Stephens, T, & Morris, 2007). Significant research database in turbomachinery, suggests that an interruption occurs in the overall turbine aerodynamics and blade thermal load, due to the high pressure and temperatures around 2000-C, resulting in leakage flow approaching the tip of the blade and rapid acceleration, thus forming an in-line flow over the blade edge leading to form flow separationvortices generated due to the energy from the flow mixing with passage flow and therefore increasing the aerodynamic loss.

This research is aiming to establish a comprehensive insight into the knowledge gap and develop knowledge backed improvement, by exploring the appropriate method for leakage flow reduction in the turbine stage with optimized studies.

Biography

A Kingston University 2019 Graduate, with an Integrated-Master's Degree award in Aerospace Engineering. Since Graduation, I had two career pathways in engineering as: Metrology Applications Engineer, and AutoCAD specialist (Architectural drawing). Experienced in working for Blue-Chip customers as a contractor, in a variety of sectors including Aerospace, defence, Automotive, Motorsports and marine. I'm Fascinated by the fast developments in engineering, corresponding to the last fifty years, this has refined my interest in Aerodynamics and working experience with Turbomachinery has complimented my interest to become an internationally recognized researcher, providing a positive contribution in efficiency and enhanced performance to the cleaner future aviation.

Currently a CFD intern to research and develop Hydrogen-Fuel cell technology with Bramble Energy Limited, alongside my PhD research.
