Effect of the spray cone angle in the spray cooling with R134a

Experimental Thermal and Fluid Science, 2013
Spray cooling experiments were performed to study the effect of the spray cone angle on heat transfer and film thickness. The experiments were carried out for three different types of nozzles. Results for heat transfer and film thickness for different flow rates are presented working with the dielectric refrigerant R134a and on a heater with low ...

A numerical and experimental investigation on the coefficients of discharge and the spray cone angle of a solid cone swirl nozzle

Experimental Thermal and Fluid Science, 2004
Abstract Numerical and experimental investigations have been made on the coefficient of discharge C d and the spray cone angle ψ of a swirl spray solid cone pressure nozzle. The theoretical predictions are made from a numerical computation of flow in the nozzle using the standard k – e model of turbulence.

Optimal nozzle spray cone angle for triangular-pitch shell-and-tube interior spray evaporator

International Journal of Heat and Mass Transfer, 2015
Abstract The present study proposed a triangular-pitch shell-and-tube spray evaporator featuring an interior spray technique. In the proposed approach, the nozzle tubes are positioned within the tube bundle in such a way that the surface of each heater tube is sprayed simultaneously by two cooling sprays.

Effect of flow conditions on spray cone angle of a two-fluid atomizer

Journal of Mechanical Science and Technology, 2011
A visual study is conducted to determine the effects of operating conditions on the spray cone angle of a two-fluid atomizer. The liquid (water) jets exit from peripheral inclined orifices and are introduced into a high-speed gas (air) stream in the gravitational direction.

Empirical correlation for spray half cone angle in plain-jet airblast atomizers

open access: yesFuel, 2020
Abstract Plain-jet airblast atomizers are widely used in industrial applications. The literature contains numerous papers on Sauter mean diameter, however, there is no estimation method available for spray cone angle, SCA, which derivation is the primary goal of this study. Four distinct, practical model liquids were analyzed: distilled water, diesel

Transient Spray Cone Angles in Pressure-Swirl Injector Sprays

SAE Technical Paper Series, 2004
<div class="htmlview paragraph">The transient cone angle of pressure swirl sprays from injectors intended for use in gasoline direct injection engines was measured from 2D Mie scattering images. A variety of injectors with varying nominal cone angle and flow rate were investigated.
