In this paper, the behavior of cone-jet mode fluid by electrohydrodynamic atomization (electrospray) is numerically simulated and investigated with effect liquid wetting corona discharge effects. The simulation was performed contact angle condition to fit Taylor cone shape experiments. Experimental data are provided verify validate numerical method, followed additional analyses on effects elect...

Two single parameter families of polyhedra P (ψ) are constructed in three dimensional spaces of constant curvature C(ψ). Identification of the faces of the polyhedra via isometries results in cone manifolds M(ψ) which are topologically S × S, S or singular S . The singular set of M(ψ) can have self intersections for some values of ψ and can also be the Whitehead link or form other configuration...

In cookware industry, interior spray coating process is an important process to protect the cookware product from the corrosion. In this process, the coating material “TEFLON” is used to spray to cover all the part’s surface. If a pot or pan is not too deep, one spray gun is enough to spray to cover all the interior surface. However, for the high side-wall pot, two spray guns must be used to sp...

Engine efficiency and emissions depend on the fuel atomization dispersion. The dispersion heavily ambient pressure temperature. In this work, to study Diesel sprays in engine conditions, an electrically heated, constant-volume, pressurized vessel was designed manufactured. controlling electronics software were developed tested ensure safe precise operation. A commercial Bosch six-hole automotiv...

Detrimental effects to quantitative interpretation of Mie and laser-induced fluorescence images of hollow-cone sprays were investigated. The attenuation of the laser beam leads to locally unknown intensities rendering it impossible to obtain high-fidelity images of these sprays. Two strategies that use bidirectional illumination of the spray are discussed and evaluated. Conditions for which a b...

This research was conducted with the goal of clarifying the required conditions of water-saving showerheads. In order to this, the research analyzes the mutual relationship between water usage flow, the level of satisfaction and the physical properties of spray of showerheads. The physical properties of spray were measured using physical properties test apparatus of standard or scheme for water...

Spray cooling of a hot surface was investigated to ascertain the effect o f nozzle-tosurface distance on critical heat flux ( CHF). Full cone sprays of Fluorinert FC-72 and FC-87 were used to cool a 12.7 X 12. 7 mm 2 surface. A theoretical model was constructed that accurately predicts the spray's volumetric flux (liquid volume per unit area per unit time) distribution across the heater surface...

, 135
and 140
spray angles. the amount of fuel injected per cycle is constant at all s...
