In this paper, the modeling of liquid contaminant fluid dynamics for the associated emission-diffusion process induced by environmental changes is investigated. Due to the contaminants and large fluid liquids interaction, the contaminant diffusion causes the concentration structure to be strong uncertainty. Parameters related to the contaminants concentration distribution, including the emission,...
In this paper, a model-based contaminant distributed prediction approach based on the combined static nonlinear dynamics and linear dynamics structure is developed to predict the contaminant concentration in environmental fluid diffusion process. Finite element analysis could achieve a near perfect result in computing the contaminant concentration field in predicted water field. However, the finite...
In this paper, the diffusion nonlinear modeling strategy based on time-space separation approach is proposed for contaminant concentration advection-diffusion process which described by partial differential equation with uncertain nonlinear distributed diffusion. The time-space separation approach is proposed to deal with the contaminant temporal-spatial distribution characteristics, which the spatiotemporal...
The Poyang Lake Ecological Economic Zone is important in Chinese ecological civilization construction, land development; regional coordinated development and rising Jiangxi. So we must plan scientifically and construct on a high level. We should promote Jiangxi rise by relying on abundant natural resources, rational use of various favorable conditions, adopting effective measures, comprehensive environmental...
The application of construction technology of hydraulic fill with sand in high type road in China had made numerous social and economic benefits, but from some successful examples of using this technology, we can know that most of them have certain limitations and it has not developed completely. In this paper, the research of preparatory work, construction technology, environmental protection, quality...
