Research interests

1. Hydraulic Power Transmission and Control. The research interest includes two main fields: A) According to the characteristics of machinery and equipment, the hydraulic power transmission and control system is designed and optimized, to investigate the dynamic characteristics of hydraulic systems, pressure loss, energy saving, synchronization and other aspects; B) Study the electrohydraulic control theory and methods, electro-hydraulic proportional / servo control technology successfully applied in the mechanical engineering industry, to improve the control accuracy and automation of the mechanical equipment, including mining, metallurgical, engineering, agricultural, water conservancy machinery, and so on.

Effect of input flow rate on one system pressure response: (a) Oil source, (b) Measured hydraulic valves, (c) Pressure response

2. Computational Fluid Dynamics Technique and its Applications. Computational Fluid Dynamics (CFD) is a kind of numerical simulation technique which can study single-phase flow: gas, liquid, particle, or multipase flow: mixture of two or three phase. The research interest includes theoretical basis and experimental study of flow characteristics, multi-field coupling mechanism, multiphase flow in fluid machinery.

Some results of CFD simulation: (a) Grid in the region of boundary layer, (b) Partial pressure contour, (c) Streamline of fluid

3. Hydro-viscous Clutch for High Power Mechanical Equipment. In order to study the speed regulation and soft-start process of high power fan, water pump, marine engine, nuclear pump, belt conveyor and other common mechanical equipment, we developed a high power hydro-viscous clutch (wet clutch) based on the theory of fluid mechanics. The whole transmission efficiency and energy saving effect, as well as the structure and temperature effect of rotating friction pair, oil film (single, multi-phase) dynamic characteristics are investigated, to improve the single-machine capacity of domestic equipment.

4. Hydraulic shock absorber and its experiment rig for car. The research interest includes the design and development of hydraulic shock absorber and its experiment rig, which is mainly used in cars. The hydraulic shock absorber has a dual-tube structure, and which is controlled by two integrated solenoid valves, and may gain multi-stage adjustable damping effects. The shock absorber consists of three chambers: rebound chamber, compression chamber and reserve chamber, and one compressive air room. The characteristics of force-displacement and force-velocity during its working process are investigated via simulation and experiments.
