The results of the 13th Chinese College Student of the Year-Nomination Award were announced recently. You Ruquan, a PhD candidate from the School of Energy and Power Engineering of Beihang University, was honored with the Nomination Award.
In September 2013, You Ruquan, ranking the first in academic performance, was recommended for admission to Beihang University from Nanjing University of Aeronautics and Astronautics without requiring entrance examination. He was qualified to study for a doctor's degree in advance with his excellent academic performance and scientific research abilities the next year. During his postgraduate and doctoral study, You Ruquan, instructed by Prof. Tao Zhi and Prof. Li Haiwang, was mainly engaged in the research of advanced cooling technology of aero-engine turbine blades. He was awarded many scholarships and awards including ASME ITGI Scholarship, second prize of Innovation and Entrepreneurship Scholarship of Ministry of Industry and Information Technology, Fund for Excellent Academic Doctors of Beihang University, American Society of Mechanical Engineers International Gas Turbine Institute ( ASMEIGTI) Scholarship (only 20 people worldwide can receive the award each year), etc. He applied for seven national invention patents, of which four items have been authorized. Besides, he obtained the authorization of two national practical new-type patents.
You Ruquan sets strict demands on himself in all respects, and he always puts priority on scientific research. After entering Beihang, he built the first test-bed together with his fellows in the laboratory for testing the rotating flow field of aero-engine high-pressure turbine blades. Focusing on basic research, this test-bed aims at providing experimental data and theoretical support for research of aero-engine in China.
He has achieved a series of scientific research results after years of effort. He, for the first time, discovered the phenomenon of flow separation in the cooling channel of turbine blades in the rotation circumstances and the mechanism of internal heat transfer deterioration, and found reasons of partial ablation of high-pressure turbine blades, which provides theoretical support for the refinement design of turbine blades in China. His article Measurement of the mean flow field in a smooth rotating channel with Coriolis and buoyancy effects was published in ASME Turbo, the top-level conference in this field, and was highly praised by the chief technology expert of Florida Turbine Technologies, Inc. This conference paper was also recommended for publication in top journal of gas turbines J. Turbo.
Trials and hardships, all these experiences will always inspire him to realize his dream, move towards the larger stage and continue to create miracles.
