高速液体吐出モデルの確立

抄録

Liquid jet is used in industries. However, the relationship between pressurization and jet speed have never been established, because the jet phenomenon contains a lot of fluid dynamics factors, for example, physical property, container shape and profile of pressurization. The purpose of this study is, therefore, to develop the physical model for liquid jet ejection. We performed experiment and numerical simulation using ANSYS/FLUENT and MATLAB. We found high correlation between outlet velocity and pressure. Also, we found that the liquid jet is ejected as compressible liquid in the beginning but the behavior changes from compressible liquid to incompressible liquid over time.
