Effect of leakage flow from guide vanes on erosion of the runner of a Francis turbine [PDF]
International Journal of Fluid EngineeringFor Francis turbines, the importance of guide vanes in efficient operation is to provide optimum flow conditions to the runner. This requires a clearance gap to be provided at the ends of the guide vanes.

Non-Uniform Clearance between Rotor Surfaces and Its Effect on Machine Performance in Twin-Screw Compressors [PDF]
, 2012 The performance of twin-screw compressors is primarily affected by the clearance between a pair of meshing rotors. This study proposes a method for calculating the normal clearance along the contact line between rotors using two normal rack curves, which

The value of statistical life and cost–benefit evaluations of landmine clearance in Cambodia [PDF]
, 2010 Development agencies spend approximately US$ 400 million per year on landmine clearance. Yet many cost–benefit evaluations suggest that landmine clearance is socially wasteful because costs appear to far outweigh social benefits.

Evaluation of different erosion models for predicting guide vane wear in Francis turbine
Frontiers in Mechanical EngineeringGuide vanes (GVs) are one of the components of the Francis turbine that are most vulnerable to erosion. Presence of hard minerals including feldspar and quartz cause erosion on the surface of GVs.
