Abstract
ABSTRACT A parametric study on impinging atomization of gelled fluid is conducted by preparing the simulants and establishing impinging platform. We observe the spray behavior and measure the breakup lengths, spray inclined angles and SMDs (Sauter Mean Diameter) under different jet velocities, impinging angles, skewnesses as well as pre-impinging lengths. The experimental data is also compared to theory. Present results indicate that spray behaviors can be divided into three categories for different jet velocities. Spray angle of the sheet is increased with the increase of the impinging angle. Only a few droplets are produced when impinging angle is 30° revealing a poor atomization quality. Breakup lengths and SMDs decrease as jet velocities and impinging angles are improved. Skewed impingement always gives smaller breakup lengths and SMDs than non-skewed injector, that is, skewness is in favor of impinging atomization. With enhancing the pre-impinging lengths, breakup lengths decrease gradually, but an optimal value exists for the SMD. Moreover, comparison shows that experimental breakup lengths and SMDs agree very well with the theory in high Web number range, however, theoretical results leave an overestimation at low Web number.
