累积流量坐标系下河流二维水质模型流管划分技术研究

Research on Stream Tube Division Technology for 2D Water Quality Model Under Accumulative Flux Coordinate System

针对广泛应用的河流累积流量二维水质模型手工流管划分存在的缺陷,提出了计算机流管划分的原理,并给出了详细的计算机流管划分的步骤、方法和应用实例。该方法具有很强的可编程性,能极大地减轻科研人员的劳动强度,提高科研效率,增加计算方案的灵活性。

According to the existed weakness of stream tube divided by handwork in the widely applied river 2D water quality model of accumulative flow rate, the principle of stream tube divided by computer is put forward and the detailed divided steps, methods and an applied case of stream tube divided by computer are given in this article. This method has very strong programmable character. It can largely alleviate labor strength of scientific researcher, raise efficiency of scientific research and increase flexible quality of calculation schemes.
