The Influence of Fluid Viscosity of Fluid Jetting Dispensing
High Density Design Packaging and Microsystem Integration, 2007 International Symposium on, 2007Fluid viscosity is a very important factor for fluid dispensing, and it has important effect on the volume and velocity of the fluid that jetting from the nozzle outlet. This paper analyses the force that the fluid gives to needle both with low and high viscosity situation and establishes formulas.

Physics of Fluids, 2004
Similarity solutions for laminar two-fluid jets and wakes are derived in the boundary-layer approximation. Planar and axisymmetric fan jets as well as classical and momentumless planar wakes are considered. The interface between the immiscible fluids is stabilized by the action of gravity, with the heavier fluid, taken to be a liquid, placed beneath ...

The steady cone-jet mode of electrospraying close to the minimum volume stability limit
Journal of Fluid Mechanics, 2018We study both numerically and experimentally the steady cone-jet mode of electrospraying close to the stability limit of minimum flow rate. The leaky dielectric model is solved for arbitrary values of the relative permittivity and the electrohydrodynamic

Impinging free jets of ideal fluid
Journal of Fluid Mechanics, 1998This paper studies the impinging of two ideal fluid jets. The usual two-dimensional model of jet flow uses an ideal, incompressible, weightless fluid to describe these impinging jets, so that the problem becomes one of complex analysis which seems to have an infinite number of analytical solutions, except for direct jet impacts.

Edge effect in fluid jet polishing
Applied Optics, 2006The edge effect is one of the most important subjects in optical manufacturing. The removal function at different positions of the sample in the process of fluid jet polishing (FJP) is investigated in the experiments. Furthermore, by using finite-element analysis (FEA), the distributions for velocity and pressure of slurry jets are simulated ...

Steady horizontal jet in a stratified fluid
Mechanics Research Communications, 1991Classical Schlichting's solutions for a steady laminar round or planar jet in a homogeneous fluid demonstrate that a longitudinal velocity \((U_ 0)\) on the jet axis depends on distance \((x)\) from the jet origin as \(U_ 0\sim x^{-1}\) (round jet) and as \(U_ 0\sim x^{-1/3}\) (planar jet).

Fluid jet polishing of steel moulds
SPIE Proceedings, 2016Fluid Jet Polishing (FJP) is a novel polishing technology, which experienced growing interest for niche applications over the recent years. This publication suggests FJP for processing of steel moulds for plastic injection moulding. These moulds are typically finished manually by skilled experts to date.
