| 1 | Numerical investigation of influence of wave directionality on the water resonance at a narrow gap between two rectangular barges显示文摘A three-dimensional time-domain potential flow model with second-order nonlinearity was applied to simulate the wave resonance in a gap between two side-by-side rectangular barges. In the model, the velocity potential was decomposed into the incident potential and unknown scattered potential which was obtained by solving the boundary integral equation. The fourth-order predict-correct method was applied to enforce the free surface conditions in the time integration. The influence of the wave direction on the first and second-order gap surface elevations was investigated. The results reveal that the incident wave angle does not affect the resonant wave frequency and the maximum surface elevation at resonance always occurs at the middle location along the gap.However, the corresponding maximum wave surface elevation at resonance varies with the incident wave angle.The location of the maximum wave elevation shifts either upstream or downstream along the gap, depending on the relative magnitude of incident wave frequency to the resonant frequency. | JIN Ruijia TENG Bin NING Dezhi ZHAO Ming CHENG Liang | 2017 | Acta Oceanologica Sinica2017，36，6： | 3 |
| 2 | Experimental study on gas–liquid dispersion and mass transfer in shear-thinning system with coaxial mixer显示文摘The effects of impeller type, stirring power, gas flow rate, and liquid concentration on the gas–liquid mixing in a shear-thinning system with a coaxial mixer were investigated by experiment, and the overall gas holdup, relative power demand, and volumetric mass transfer coefficient under different conditions were compared. The results show that, the increasing stirring power or gas flow rate is beneficial in promoting the overall gas holdup and volumetric mass transfer coefficient, while the increasing system viscosity weakens the mass transfer in a shearing–thinning system. Among the three turbines, the six curved-blade disc turbine(BDT-6) exhibits the best gas pumping capacity; the six 45° pitched-blade disc turbine(PBDT-6) has the highest volumetric mass transfer coefficient at the same unit volume power. | Baoqing Liu Yijun Zheng Ruijia Cheng Zilong Xu Manman Wang Zhijiang Jin | 2018 | Chinese Journal of Chemical Engineering2018，26，9： | 1 |
