Newsletter 2019.3 Index
We participated in the 16th flowing dream contest held in Muroran city, Hokkaido on 29th November 2018 with team name "Watasepa." The team name "Watasepa" was named from “Water” and “Separate”.
"Watasepa" is a team composed of five members of Meisei University's Faculty of Science and Engineering, Department of Mechanical Engineering.
2. Reason for choosing this theme
The theme of the 16th “Flow Dream Contest” was "Active Control of Flow" and we thought based on the theme. We focused on the marine pollution by plastics which is often featured in the news because marine pollution is getting worse year by year and sea creatures that die due to marine pollution. Therefore, we thought that we could solve the problem of marine pollution, and that solution was “The Water Surface Control Device " we created.
3. About our production
We attempted to generate a vortex, but it was difficult. Therefore, we thought to generate vortex more easily, installed a control board in the circulating water tank, and separated and collected the floating waste on the surface of water using the vortex behind that control board.
As a result, we can separate and collect two types of waste, large and small.
First, FIG. 1 shows how to collect large floating waste on the water surface. Large floating waste on the water surface are caught in a vortex made by a control board with a large diameter and a high probability.
Second, floating waste on the water surface passing through the control board of FIG. 1 is collected by the control plate shown in FIG. 2.
FIG1. Controll Board1
FIG2. Controll Board2
We have created “The Water Surface Control Device ". “The Water Surface Control Device " can separate and collect two types of waste, large and small.
We expect the marine pollution to be solved by “The Water Surface Control Device ".
And we are grateful to the contest executives committee, the Meisei University’s professors and the people who supported us.
