基于OpenMP并行架构的浅水湖泊水动力水质模型研究
Research on the hydrodynamic water quality model of shallow water lakes based on OpenMP parallel architecture:a case for Tuohu lake
摘要
Abstract
To improve the computational accuracy and efficiency of the two-dimensional hydrodynamic water quality coupled numerical model in shallow lakes,this paper took the 2018 Tuo Lake water environment simulation as an example.It applied OpenMP parallel computing technology to the development of the two-dimensional hydrodynamic water quality coupled nu-merical model for shallow lakes.Three evaluation methods including the average absolute error,root mean square error,and spearman correlation coefficient were introduced to compare and analyze the accuracy and speed of the self-developed model and the MIKE21 model simulation results.In terms of hydrodynamic verification,the average absolute error and root mean square error of the self-developed model and MIKE21 model compared to the measured values were controlled within 0.1 m and 0.2 m,respectively,showing strong correlation.Under the scenario of a single point source pollution emergency,the trend of pollution concentration changed at each monitoring point simulated by the self-developed model and MIKE21 was basically consistent,and the error statistical value was controlled within a range of 0.1 m.Moreover,the computational speed of the self-developed model had increased by 10 times compared to MIKE21.The research results indicated that the efficient hydrody-namic water quality coupling model for shallow lakes can achieve a balance between accuracy and efficiency,providing techni-cal support for the simulation analysis of hydrodynamic water quality in lake areas and the improvement of water environment quality.关键词
