摘要
以海上溢油应急反应地理信息系统(GIS)为平台,采用贴体坐标变换,提出一种应用于海上溢油应急反应系统中流场计算的快速贴体网格生成算法,并实现了在GIS平台上自动生成以电子海图上实际海域为背景的贴体坐标网格。该网格生成方法和技术在溢油应急反应系统中,为实现流场计算提供了快速、直观、方便的条件。通过对渤海海域的两个算例表明,本文提出的贴体网格快速生成方法和技术能够满足海上溢油应急反应中流场计算的需要,取得了较好的效果。
The paper puts forward a kind of fast generating algorithm of body-fitted grid, which is applied to the tide field calculation in the marine oil spill response system, taking MOSR-GIS as a platform. The body-fitted coordinates conversion is adopted.. The body-fitted grids can be generated in the chart on the GIS platform automatically. This method and technique can offer quick, direct and convenient conditions for the tide-field calculation. The calculation example indicates that it can be satisfied to apply to the tide-field calculation in the marine oil spill response system.
