Dynamic response of a shaft of a Pelton turbine due to impact of water jet

Performance and reliability of any rotating machine can be studied by proper dynamic analysis of the machine. In this regard, this paper presents the method to study the dynamic response of the shaft of a Pelton turbine due to the impact of water jet. Equations of motion for the bending vibration of Pelton turbine assembly, in two transverse directions, is developed by using Lagrange equation o...

investigation of supersonic jet into compressible subsonic cross flow on the surfaces around the jet exit

an experimental study has been performed to investigate the flow physics of an under-expanded axisymmetric supersonic jet exhausting transversely from a flat plate into a subsonic compressible cross flow. the goal was to study the effects of boundary layer thickness ratio (δ/d) and the jet to free stream dynamic pressure ratio (j) on surface pressure. the resulting measurements distinctly show ...

Minimal water-jet hydrodissection

This paper presents a hydrodissection technique performed with high-speed pulse injection of only 0.1 cc liquid and assess its efficacy, safety, and the level of reduction in posterior capsule rupture complications in phacoemulsification cataract surgery. The kinetic energy of moving objects is directly proportional to the mass and to the square of its velocity. The high energy obtained by high...

Water jet-assisted lipoplasty.

Water jet-assisted lipoplasty channels a thin, targeted, fan-shaped jet into adipose tissue to loosen tissue structure and release adipocytes. According to the authors, water jet-assisted lipoplasty facilitates preinfiltration of modified tumescent solution to create analgesia, resulting in painless or near painless lipoplasty. The authors contend that, with this method, patient safety has incr...
