Effect of Tip Clearance on Hydraulic Performance of Water-jet Pump
The k-ω Shear Stress Transport (SST) turbulence model is adopted to study the hydrodynamic performance of the water-jet axial pump which is applied in Unmanned Surface Vehicle (USV). The numerical simulation of the whole passage of the water-jet pump is carried out for four different tip clearance with δ = 0.3 mm, δ = 0.8 mm, δ = 1 mm and δ = 1.4 mm. And the results, in term of external charact...
متن کاملMinimal 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...
متن کاملWater 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...
متن کاملQuadratic spatial soliton generation by seeded downconversion of a strong harmonic pump beam: errata.
Two-dimensional quadratic spatial solitons were generated experimentally near phase-matching conditions for type II frequency doubling in KTP by the seeding of a strong second-harmonic field with a weak input at the fundamental wavelength. The self-trapped beams were shown to be insensitive to the energy, phase, and polarization of the fundamental-frequency seed input beam.
متن کاملDynamic 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...
