Numerical simulation and experimental investigation for oil spill transport characteristics of trapezoidal open channel in water transfer
摘要
Abstract
For the need of rapid response to sudden oil pollution accidents in the long distance water transfer project, two-dimen-sional hydrodynamic and oil spill numerical simulation and experimental model were employed to investigate the transportchar-acteristics for oil spill in the trapezoidal open channel. T he results indicated thatdue to the large variation of velocity distribution atthe horizontal cross-section of the trapezoidal open channel, the longitudinal length of oil slick depends on the middle velocity of open channel after sudden oil pollution accidents, and its variation rate is 0. 5 times of the middle velocity and less affected by the oil-spilled location, wind, and slope coefficient. The results can predictthe oil spill scope quickly and provide technical sup-portfor the emergency disposal and regulation.关键词
