|Abstract:||At optimal angle of attack, vanes have the maximum strength of secondary circulation. For the same hydraulic condition, the maximum strength of vane induced secondary circulation also depends on their shapes. Optimal angle of attack in case of rectangular submerged vane with collar is very close to 40° where as in case of double curve vane type I, double curve vane type II, J1 type and J2 type vane is very close to 45°. Strength of vane induced secondary circulation in terms of moment of momentum depends upon various parameters. A dimensional analysis approach has been attempted to get dimensionless moment of momentum. The maximum strength of vane induced secondary circulation in terms of dimensionless moment of momentum is greater in case of rectangular vane than that in case of curved vanes in the same flow conditions and same height and length of vanes. © 2006 Taylor & Francis Group, LLC.|
