Experimental Research on Gas/Liquid Coaxial Swirling Nozzle

摘要

In this paper,Particular research on two kinds of gas/liquid coaxial swirling nozzle for their spray flow field had been done with the support of Phase Doppler Particle Analyzer (PDPA) ,the results of drop parameter in spray flow field under cold flow simulation, normal pressure and burning condition were acquired, and the necessary spray condition to get stably burning flame under normal pressure were also obtained. Finally atomization performance under normal pressure and burning condition were analyzed. Simultaneity, the structure and technical trait of the two kinds of gas/liquid coaxial swirling nozzle,the tester,survey equipment and experimental design are introduced in the article.
