Abstract
Inside the car engine, it is important to control the generation of liquid film and liquid film behavior. The objective of this study is to clarify the mechanism of scattering and apply the CFD model. We have changed flow rate of liquid film and cross-flow velocity, and have taken liquid film behavior in the steady flow using high speed video camera. Wave frequency and liquid film thickness are obtained to find correlation with liquid film behavior. The flow pattern changes into wave, transition, and scattering region in the experimental range. The transition region exists around U_a = 15[m/s]. And in U_a > 15[m/s], transition region exists around t_<avg> = 1[mm] and f = 40[Hz].
