When studying the flow dynamics and the characteristics of fluid motion,vortex structure with their interactions is the key issue.In the present work,a vortex control method is investigated based on the vortex identification system of Liutex.The numerical
根据热力学数据,绘制了25℃条件下NdCl3-AlCl3-NH4HCO3体系在总碳浓度为1.0 mol/L条件下各组分的lg cB-pH曲线,以及在不同总碳浓度条件下Al与Nd的lg cB-pH曲线;分析了用碳酸氢铵沉淀稀土时各组分的行为。结果表明:pH在2.8~7.0范围内,可实现Nd2(CO3)3沉淀;pH在2.8~3.7范围内,铝不易与稀土共沉淀,
An iterative time-marching scheme is developed to investigate the hydrodynamic interactions between multiple ships.Such an unsteady interactive effect could be magnified in restricted waterways,e.g.,a channel or harbor area.To the author\'s knowledge,ne
Vortical structures of a submarine with appendages are fully turbulent and complex.Thus,flow control and vortex manipulation are of great importance for the hydrodynamic performance and acoustic characteristics.Take the generic submarine model DARPA Subof
The incompressible unsteady Reynolds-averaged Navier-Stokes(URANS)simulations are performed for a free-running container ship in maneuvering conditions:the starboard and portside turning circle simulations with 35° rudder deflection.The validation variabl
For complex aerodynamic and hydrodynamic problems,the analysis of vortex is very important.The Liutex method is an eigenvalue-based method which is local,accurate,and unique,which can give an accurate definition of vortex,so the control of vortex can be i
This paper proposes a 3-D non-hydrostatic free surface flow model with a newly proposed general boundary-fitted grid system to simulate the nonlinear interactions of the bi-chromatic deep-water gravity waves.First,the monochromatic bidirectional and bi-ch
研究了在工业电解槽中利用人工铜柱模拟结瘤及其生长行为,考察了电解时间和结瘤初始高度对结瘤形貌和生长速率的影响。结果表明:阴极电流随极间距减小而显著增大;电解时间小于12 h,结瘤形貌变化不大;电解时间延长至24 h,7.5 mm是结瘤形貌显著变化的临界高度:当结瘤初始高度大于7.5 mm后,其顶端出现明显的冠状膨大;当阴极板表面的结瘤高度小于2.5 mm且电解时间小于12 h时,其径向生长速率较快;除此以外,均以轴向生长为主导。
