摘要: 本文根据提出的旋流喷射锥膜雾化理论,由旋流喷射的作用力关系,求导出压力旋流喷射雾化的喷雾角特性关系式:θ=tg-12·(1-φ) 并将各种喷雾角关系式同实验数据进行比较。结果表明:本文所导出的喷雾角关系式与实验数据有较好的接近,而且计算式也较简单,有一定的实用价值。Abstract: Based on the suggested atomisation theory for the swirl spray conical film, the formula for the spray angle characteristic of pressure swirl spray atomisation θ=tg-12·(1-φ) is derived from the relation of acting forces in swirl spray.The spray angle characteristics of swirl spray are worked out with various formulas and compared with actual test data. The results show that the derived formulas for spray angle in this article agree comparatively well with the results from experiments, and that the expressions are simple. They are of definite value in practice.
