TL;DR: In this paper, a combined process with EDM, ECM and electroforming was proposed for the production of precision nozzles with small diameters and various inner shapes, which were successfully produced with good concentricity to the outer profile.

TL;DR: Theoretical predictions of air core diameter, coefficient of discharge and spray cone angle of a swirl spray pressure nozzle have been made from numerical computations of flow within the nozzle as mentioned in this paper.

TL;DR: In this article, an ultrasonic ultrasonic spray system was designed for selective membrane formation, which can tolerate poly(furfuryl) tages over polymer membranes, but only if they can be alcohol in acetone (30 wt.%) fabricated readily and reproducibly.

TL;DR: In this paper, the initial angles of liquid jets were measured at room temperature by a spark photography technique and the measured trends were then discussed in the light of possible mechanisms of the breakup process and shown to be compatible with the aerodynamic theory of surface breakup if modified to account for nozzle geometry effects.
Abstract: Liquid jets are considered issuing from single-hole, round nozzles into quiescent gases under conditions such that they break up into a well defined conical spray immediately at the nozzle exit plane. The initial angles of such sprays were measured at room temperature by a spark photography technique. Water, n-hexane, and n-tetradecane at pressures from 11.1 MPa to 107.6 MPa were injected into gaseous N2 at pressures from 0.1 MPa to 4.2 MPa through sixteen nozzles of different geometry. Under the test conditions, the spray angle is found to be a strong function of the nozzle geometry and the gas-liquid density ratio and a weak function of the injection velocity. The measured trends are then discussed in the light of possible mechanisms of the breakup process and shown to be compatible with the aerodynamic theory of surface breakup if modified to account for nozzle geometry effects.

TL;DR: In this article, the authors investigated the effects of three major parameters on micro-combustion, namely hydrogen to oxygen mixing ratio, nozzle to combustor diameter ratio, and wall thickness-to-cocktail diameter ratio.
