| 1 | Numerical study of hydrofoil surface jet flow on cavitation suppression显示文摘Cavitation caused vibration and noise of hydraulic machinery. To some extent,cavitation made fatigue damage in advance. Many scholars found that the re-entrant jets were the reasons of the shedding of cavities. To suppress cavitation,based on the idea of blocking the re-entrant jets,a special surface flow structure of 2D hydrofoil was proposed. The through-hole was made in the proper position of the hydrofoil. The incoming flow can outflow from this jet-hole automatically depending on the pressure difference between pressure side and suction side. Re-entrant jet growth can be weakened by optimizing the jet-hole geometry. Based on the standard k-ε turbulence model and Schnerr & Sauer cavitation model,under different cavitation numbers( σ) and jet-angles( β) for NACA0066( 2D) hydrofoil with 8° angles of attack,cavitation field numerical analysis was carried out. The results show that 2D hydrofoil cavitation flow had a strong unsteadiness. Making a jet-hole at the junction between the re-entrant jet and cavity can effectively minimize cloud cavitation. For a certain cavitation condition,optimal jet-angles( β) can be obtained to control cavitation growth. For the same β,the effects of cavitation suppression were changed with different cavitation numbers( σ). Consequently,suitable jet-angle and jet-position could extend the stable operating range of the hydrofoil. | WANG Wei LU Shengpeng XU Ruiduo YI Qi WANG Yayun WANG Xiaofang | 2017 | 排灌机械工程学报2017，35，10： | 5 |

| 3 | Stimulated Brillouin scattering induced all-optical modulation in graphene microfiber显示文摘Graphene microfibers are burgeoning modulators with great potential in all-optical communication. One of the critical issues that remains to be understood is the dynamic mechanism of light–graphene interaction. Here, we propose a power dependent modulation by using 980 nm pump light and 1064 nm signal light via graphene microfiber, and the results show a strong transmission reduction and frequency blue shift with the increase of pump power. The experimental observation is attributed to a stimulated Brillouin scattering process induced by the pump light. Power and frequency variations are a result of energy transition of the scattered phonon in the fiber. This work reveals the nonlinear effect process in the light–graphene interaction and provides a new method for power and frequency control with graphene all-optical modulation. | JIWEN ZHU XUEMEI CHENG YALI LIU RUIDUO WANG MAN JIANG DIAO LI BAOLE LU ZHAOYU REN | 2019 | Photonics Research2019，7，1： | 1 |
| 4 | Bovine Serum Albumin Detection by Graphene Oxide Coated Long-Period Fiber Grating显示文摘A biosensor for bovine serum albumin(BSA)detection by graphene oxide(GO)functionalized micro-taped long-period fiber grating(GMLPG)was demonstrated.The amide bond connected between the GO and BSA enabled the BSA to attach onto the fiber surface,which changed the effective refractive index of the cladding mode and characterized the concentration of the BSA.This real-time monitoring system demonstrated a sensing sensitivity of 1.263 nm/(mg/mL)and a detection limit of 0.043 mg/mL.Moreover,it illustrated superior measurement performance of higher sensitivity in the presence of glucose and urea as the interference,which showed static sensitivities of~1.476 nm/(mg/mL)and 1.504 nm/(mg/mL),respectively.The proposed GMLPG demonstrated a great potential for being employed as a sensor for biomedical and biochemical applications. | Ruiduo WANG Hao WU Mei QI Jing HAN Zhaoyu REN | 2022 | Photonic Sensors2022，12，3： | 0 |
