| 中文摘要 |
| 本文对风引起海面油膜的漂移速度的关系,通过水面紊动剪切应力的平衡理论,推导出风系数的近似计算公式。结合有关现场观测资料和风洞模拟试验结果,确定油膜的风漂移速度与风速之比的经验系数为1.6-3.5%。 |
| 英文摘要 |
| The relationship between the advection of oil slick on the sea surface and the wind speed has been studied in this paper. An approximate formula used in calculation of ratio of the wind-driven currents to the wind speeds is derived itself from consideration of the balance between the trubulent shear stresses on the air-sea interface. Combining the field observation and the wind-tunnel experiments in the laboratory, it is established that the wind factor, i.e. the ratio of wind-driven currents to the wind speeds, is roughly 1.6-3.5%. The results obtained in this paper are available to the projects and techniques for controlling an oil spill and recovering the oil after an oil spill. |
