1945 Numerical Analysis of Contraction/Inversion of a Slab Liquid Jet
Details
Contraction and inversion of a slab liquid jet occur as a result of surface tension forces. Numerical analysis of contraction and inversion of a slab liquid jet was conducted by the VOF method. Computational results qualitatively agree with the experiment measurements. The contraction length, however, is 20% larger than the experimental value. The discrepancy is considered due to the ignorance of the nozzle. Given H the width of the jet, We the Weber number, and L the contraction length, the contraction number is defined by C=L/(H We^∧0.5). A theoretical value of 1/4 is proposed based upon examinations of the flow field.
