Abstract

With the first turbojet engine patented by Sir Frank Whittle in 1930 and the first flight of Dr. vomn Ohain’s jet-engine plane in 1939, the gas turbine engines (GTEs) have help thrusted many generations of aircrafts in both military and commercial applications. This forum will introduce the basics of a GTE, including the principle, most concerned terminologies, its performance and efficiency, as well as the commonly encountered problems such as compressor stall and surge. Compressors and turbines are essential parts for a GTE, which involves complicated aerodynamics, thermodynamics, and structural dynamics during design. Hence, this presentation will also discuss such concerns with a focus on dynamics of rotor systems.

Bio

Lili Gu conducted research at ETH Zürich and Cornell University for two years before obtaining the Ph.D. degree from Tsinghua University in July 2015. She then worked as a faculty in the Department of Mechanical Engineering at Texas A&M University (TAMU) from Sep. 2015 to July 2017. Recently, she has been offered a new position as a collaborative scientist in the School of Engineering at Swiss Federal Institute of Technology in Lausanne (EPFL).
Her research experience has been directed towards the improved dynamics and efficiency of turbomachinery, including 1) Rotor Dynamics and Vibrations 2) Conjugate Heat Transfer 3) Tribology (Thin Fluid/Gas Film Bearings) 4) Computational Fluid Dynamics and 5) Coupled Fluid-Thermal-Structural Dynamics. Her significant research outcomes include 1) theoretical models and predictive tools for the dynamics of rotor-bearing systems subject to thermal effect in turbomachinery 2) models and algorithms for the design of optimum hybrid gas bearings 3) optimized heat flux path to improve centrifugal compressor performance and 4) a provisional patent of “Variable Clearance Profile NCP Designed Hydrodynamic Journal Bearing for Reduced Power Loss.” Moreover, she has participated actively in grant application during her employment at TAMU, which has led to several projects funded both intramurally and extramurally. In addition to research, she has also actively committed in teaching work.
