Today’s marine environmental issues as well as maritime defense and security issues have become the focus of modern people's close attention. In order to solve the problem of 8 million tons of garbage flowing into the ocean every year and the Black Sea floating naval mines caused by the Ukraine-Russia war, we designed bubble walls to intercept river garbage and remove naval around ships. In order to understand the effect of the bubble wall on intercepting garbage and the extent to which the bubble system pushes away the naval mines, we designed the following three sets of experiments: the relationship between the exhaust depth and the scope of action, the relationship between the bubble emission volume and the scope of action, and the relationship between the water flow, and the relationship between the deflection angle of the water flow and the aiming error. When the bubble wall forms an angle of 45 degrees with the object's velocity direction, it can be known from the relationship between the deflection angle of the water flow and the aiming error that the best economic benefits will be achieved when the distance between the centers of the two bubbles is about 10cm. When making a bubble wall to eliminate naval mines, according to the relationship between the exhaust depth, it is known that the deeper the exhaust depth is, the more economical it can be. According to the relationship formula between bubble discharge volume, the above two groups of bubble applications are most economically beneficial when the bubble discharge volume reaches 4L/min. Based on the experimental data, we find the most cost-effective bubble wall parameters that can solve the problem of marine debris and the threat of floating naval mines.
