Abstract

The purpose of this work is development of program complex designed to simulate the spread of pollutants, including oil and petroleum products, in coastal systems, as well as transport, transformation and deposition of aerosols in air on a super-computer. The objective of this study is to develop the modules of aero- and hydrodynamics, which are part of the software package, an effective parallel method and conduct a computational experiment. For the effective implementation of the task, a parallel version of the adaptive modified alternating triangular method of the fastest descent was developed, its acceleration and efficiency were investigated. With the help of the software in question, an emergency oil spill was simulated that occurred in the Kerch Strait in November 2007. A computational experiment was also carried out to simulate the spread of impurities from motor vehicles in the coastal (recreational) area of Taganrog with and without forest plantations.The purpose of this work is development of program complex designed to simulate the spread of pollutants, including oil and petroleum products, in coastal systems, as well as transport, transformation and deposition of aerosols in air on a super-computer. The objective of this study is to develop the modules of aero- and hydrodynamics, which are part of the software package, an effective parallel method and conduct a computational experiment. For the effective implementation of the task, a parallel version of the adaptive modified alternating triangular method of the fastest descent was developed, its acceleration and efficiency were investigated. With the help of the software in question, an emergency oil spill was simulated that occurred in the Kerch Strait in November 2007. A computational experiment was also carried out to simulate the spread of impurities from motor vehicles in the coastal (recreational) area of Taganrog with and without forest plantations.

软件在超级计算机上实现了空气和水环境中污染物的扩散问题

这项工作的目的是开发一个复杂的程序，旨在模拟污染物的扩散，包括石油和石油产品，在沿海系统中，以及在超级计算机上模拟空气中气溶胶的运输、转化和沉积。本研究的目的是开发作为软件包一部分的空气动力学和流体动力学模块，一种有效的并行方法，并进行计算实验。为了有效地实现该任务，提出了一种自适应改进交替三角形最快下降法的并行版本，并对其加速和效率进行了研究。在该软件的帮助下，模拟了2007年11月发生在刻赤海峡的一次紧急石油泄漏事件。还进行了计算实验，模拟了有和没有森林种植的塔甘罗格沿海(休闲)区机动车杂质的扩散。这项工作的目的是开发一个复杂的程序，旨在模拟污染物的扩散，包括石油和石油产品，在沿海系统中，以及在超级计算机上模拟空气中气溶胶的运输、转化和沉积。本研究的目的是开发作为软件包一部分的空气动力学和流体动力学模块，一种有效的并行方法，并进行计算实验。为了有效地实现该任务，提出了一种自适应改进交替三角形最快下降法的并行版本，并对其加速和效率进行了研究。在该软件的帮助下，模拟了2007年11月发生在刻赤海峡的一次紧急石油泄漏事件。还进行了计算实验，模拟了有和没有森林种植的塔甘罗格沿海(休闲)区机动车杂质的扩散。
