Hui Hu’s Icing Research Study Receives AIAA Best Paper Honors

Martin C. Jischke Professor Hui Hu

A paper published by Professor Hui Hu and three of his students from the Martin C. Jischke Department of Aerospace Engineering has been selected to receive national recognition by the Gas Turbine Engine Technical Committee of the American Institute of Aeronautics and Astronautics ( AIAA).

“An Experimental Study on the Dynamic Ice Accretion Process over the Surfaces of the Rotating Fan Blades of an Aero-Engine Model” (AIAA 2022-2435) has been chosen to receive the AIAA Gas Turbine Engine Best Paper Award 2022. The article is co-authored by three of Dr. Hu’s former PhD students. students, including Dr. Linchuan Tian (currently a post-doctoral researcher at Shanghai Jiao Tong University); Dr. Linkai Li (currently Assistant Professor at Nanjing University of Aeronautics and Astronautics); and Dr. Haiyang Hu (currently a post-doctoral researcher at Iowa State University with Prof. Hui Hu)

Hui Hu was invited to attend the technical committee meeting at the AIAA SciTech 2023 forum next January, where the paper will be officially honored.

Student observing ice accretion in the Aerospace Engineering Department's Icing Research Tunnel.
A graduate student from the Department of Aerospace Engineering observes ice accretion in the department’s Icing Research Tunnel, which was used for the experiments in the research paper.

The paper involves an experimental campaign conducted to study the dynamic accretion of ice on rotating aircraft engine fan blades and the evaluation of icing-induced performance degradation on the fan rotor for the development of More effective and robust anti-/de-icing strategies to ensure safer and more efficient operation. aircraft engines in cold weather.

The experiments were performed in the Aerospace Engineering Department’s Icing Research Tunnel. He found, among other things, that the aerodynamic performance of a fan rotor deteriorated considerably due to the much rougher surfaces of the frosted fan blades. Needle-shaped icicles have been found to grow rapidly from the surfaces of the rotating rotor and engine fan blades under icing conditions, due to the combined effects of aerodynamic forces and centrifugal forces associated with the movement of spin. This caused huge adverse effects on the aerodynamic performance of the fan rotor.
