Internal Flow Characteristics in the Draft Tube of a Francis Turbine
Journal of the Korean Society of Marine Engineering, 2012Suppression of abnormal flow phenomena in the Francis hydro turbine is very important to improve the turbine performance. Especially, as cavitation and cavitation surge makes serious problems when the turbine is operated in the range of partial flow rate, optimum method of suppressing the abnormal flow characteristics is required necessarily. Moreover,

Internal flow characteristics of simplex swirl atomizers
22nd Aerospace Sciences Meeting, 1984The influences of main dimensions and operating conditions of simplex swirl atomizers on the thickness of the annular liquid film formed at the discharge orifice are examined. A general expression for film thickness is derived which, when compared with the experimental measurements reported in the literature, shows very satisfactory agreement over wide

Influence of Internal Objects in Flow Characteristics of Darrieus Turbine
ASME-JSME-KSME 2011 Joint Fluids Engineering Conference: Volume 1, Symposia – Parts A, B, C, and D, 2011Since Darrieus turbine is omnidirectional against the wind, it has a great essential advantage in turbulent wind environment. However, a disadvantage on the starting up is known in low velocity conditions of the wind compared with propeller turbines. Darrieus turbine has a low efficiency problem at low tip-speed ratios due to this disadvantage.

Internal Flow Characteristics of Cross-Flow Hydraulic Turbine With the Variation of Nozzle Shape
Volume 2: Fora, Parts A and B, 2007The purpose of this study is to examine the optimum configuration of nozzle shape to further optimize the cross-flow hydraulic turbine structure and improve the performance. The results show that CFD analysis for the cross-flow turbine can be adopted as a useful method to examine the internal flow and turbine performance in detail.

Hybrid conservative characteristic method for flows with internal shocks
2008A conservative hybrid scheme for the inviscid gas equations has been formulated on the basis of the characteristic relations using curvilinear coordinates. A new approximation of the metric coefficients for the moving coordinate system is suggested. The effectiveness of the algorithm is illustrated by solving: 2D and 3D unsteady shock interactions with
