영문 초록

In order to investigate the spreading performance of model canvas plates of spreading devices for oil fence by aspect ratios and spreading force FL and drag FD acting on them in a circulating water channel, 3 types of rectangular canvas plates with aspect ratios of 1/1.2, 1, and 1.2, respectively were manufactured. FL and FD is described as FL=CL(1/2)pSv² and FD=CD(1/2)pSv², where p is water density, S is the projected area of canvas, and v is current speed, respectively. The maximum spreading force coefficients CL at current speed of 0.2, 04 and 0.6 m/s were 1.5-1.6 at attack angle of 32-38° in case of aspect ratio with 1/1.2, 1.7-1.8 at attack angle of 38-44° in case of aspect ratio with 1, and 1.8-1.9 at attack angle of 40-46° in case of aspect ratio with 1.2, respectively. In addition, the ratios of CL to CD were 1.41 in case of aspect ratio with 1/1.2, 2.01 in 1, and 2.0, and 3-3.4 in 1.2, respectively.
