对海面油类漂流方向及速度的考察

EXAMINATATION ON DIRECTION AND VELOCITY OF OIL DRIFTING AT SEA

根据发生在广东省近海的“大庆236”号油轮、“拉亚埃勒”号货轮的沉船溢油事故和1989年冬、夏两季在广东省西部近海的海上油类漂流实验,对海面油类的漂流方向和速度进行了考察。经过考察认为:1)海面油类漂流方向可以用D=C_(CD)+α来拟合;2)海面油类漂流的速度基本符合U_0=U_c+§W;3)风力因子§可以简单地用(p_α/p_0)^(1/2)来确定。

Two shipwrecks occurred offshore of Guangdong Province in October 1983 and April 1984 and caused serious oil spill. The direction and velocity of oil drifting at sea in the two accidents were successfully predicated. And in summer and winter of 1989 two oil drifting experiments were conducted offshore of west Guangdong coast. It is concluded that the theory presented here was satisfying on the four cases.
