Transonic Fan Shock Noise Analysis
This project conducts a numerical simulation study on the shock noise characteristics of transonic fan rotors using the NASA Rotor 67 model. It investigates the influence of tip leakage flow on the generation, evolution, and propagation of shock-induced noise in rotors with geometric blade disturbances. The research further analyzes the effect of tip clearance on shock noise under ideal rotor conditions and explores the coupling effects between tip clearance and blade installation angle perturbations on the overall acoustic performance.
Turbine Heat Transfer Design
This project explores turbine blade thermal protection through advanced heat transfer design. By combining precisely engineered internal cooling passages, efficient external film cooling, and state-of-the-art thermal barrier coating technologies, the design enables metal components to operate safely within flame environments exceeding their melting point.
Aerodynamic Layout of Exhaust Volutes
This project investigates the aerodynamic loss and noise generation mechanisms within exhaust volutes. By establishing a sensitivity map of geometric parameters, the study identifies how shape variations influence both flow efficiency and acoustic performance. The final optimized volute model achieves a balanced improvement in aerodynamic and acoustic characteristics.
Jet Noise Control Using Azimuthal Wavy Inner Wall Design
This project evaluates the noise reduction performance of a passive control technique employing an azimuthally wavy inner wall (AWIW) configuration.

Design of High-Lift Devices for Aircraft Wings Description:
This project investigates the acoustic characteristics of high-lift devices equipped with slat tracks. Numerical simulations reveal that such configurations amplify the far-field noise radiated from the main wing, particularly under low angle-of-attack conditions (5°), where noise levels can increase by up to 10 dB.
Global Optimization of Exhaust Volute Design
This project addresses key technical challenges in the aerodynamic and acoustic optimization of exhaust volutes. An intelligent optimization method based on a parameterized geometric model was developed, integrating three-dimensional automatic optimization algorithms with detailed numerical simulations of flow and acoustic fields. The approach enables refined model optimization and performance enhancement for exhaust volute systems.
