As the most mature trend energy capture device in current technology, hydrodynamic performance of horizontal axis turbine is related to conversion entire flow energy. Based on CFD simulation software, this paper compares influence different TSRs impeller utilization and studies plus deflector hydrodynamics. Studies have shown that when TSR increases, also gradually rate adding a shroud much gre...

One of the aspects that need to be considered in designing a submarine is effect hydrodynamic aspect on resistance and maneuverability various operating conditions. In certain conditions, submarines operate conditions near seabed. general, are designed submerge surface mode. However, under Only few papers or journals have discussed their mode Several methods such as numerical physical modeling ...
