| Outline of Annual Research Achievements |
According to the research plan, a practice on the operation of experiment equipment and devices of abrasive suspension water jet system, 3D PIV system and image analysis software was conducted. Then, pre-experiment on the flow visulization of air ventilated water jet as well as image analysis were performed. Based on experiment data obtained an improved ventilation sheath has been manufactured for the experiment of next year.
