Numerical support for residual stress measurement by the hole drilling method
residual stress hole drilling method calibration coefficients FEM
2010/3/12
The hole drilling technique is one of the most frequently used methods of residual stress determination. This technique is based on drilling a small hole in the material. Relieved strain around the ho...
Improved understanding of two phase flow phenomena based on unsteady blade pressure measurement
Two phase flow unsteady pressure measurement cavitation blade pressure distribution
2010/3/15
Impeller blade and side wall pressure measurements deliver additional information of the energy transfer in a centrifugal pump under two phase flow conditions. This information is used to improve the ...
