A theory for one-dimensional incompressible jets of an ideal fluid in a constant pressure atmosphere is presented based on a general theory published earlier by the authors. Governing equations are derived for the general case of a jet in motion along a time-dependent curve.

AbstractThe quenching process within the heat treatment of workpieces can be optimized by applying locally adapted quenching conditions. Locally variable heat transfer conditions at the workpiece surface are realizable by impressing and regulation of adjustable flexible flow fields on the basis of arrays for jet flow impingings on surfaces inside the ...

A one dimensional theory of compressible inviscid fluid jets is established using a direct Cosserat type theory in contrast to procedures in which one dimensional equations are obtained by approximations of those used for a three dimensional theory. Applications are made to straight jets and circular rings.

Jet with variable fluid properties: Free jet and dissipative jet
International Journal of Non-Linear Mechanics, 2016Abstract An analysis of the laminar jet of an incompressible Newtonian fluid emerging from a narrow slot or a circular hole, where the physical properties like viscosity and thermal conductivity depends upon the temperature, is given. Both the cases: the case of In the absence of viscous heat dissipation and the case of In the presence of viscous ...

Fluid jet polishing of optical surfaces
Applied Optics, 1998We present a new finishing process that is capable of locally shaping and polishing optical surfaces of complex shapes. A fluid jet system is used to guide a premixed slurry at pressures less than 6 bars to the optical surface. We used a slurry comprising water and 10% #800 SiC abrasives (21.8 mum) to reduce the surface roughness of a BK7 sample from ...

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 ...

Precipitative Growth Templated by a Fluid Jet
Langmuir, 2005Tubular growth by chemical precipitation at the interface between two fluids, a jet and its surroundings, underlies the development of such important structures as chimneys at hydrothermal vents. This growth is associated with strong thermal and/or solute gradients localized at those interfaces, and these gradients, in turn, often produce radial ...

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.
