Abstract

The invention relates to the technical field of environment, and provides a gas dynamic distribution simulation method based on a simulation database, which comprises the following steps: matching a closest diffusion simulation model instance in the simulation database according to an actually measured first parameter group, wherein the diffusion simulation model instance at least comprises the preset first parameter group and the preset second parameter group; correcting a preset second parameter group in the matched diffusion simulation model instance by utilizing the actual measurement value of the gas concentration; and simulating the dynamic distribution of the gas concentration by using the corrected diffusion simulation model instance. Meanwhile, the invention further provides a corresponding gas dynamic distribution simulation system based on the simulation database. According to the embodiment of the invention, the simulation calculation speed can be increased, so that the problem of insufficient real-time performance caused by long time consumption of a simulation algorithm is avoided. Meanwhile, the parameters of the simulation model are corrected through the real-time concentration of the site, so that the accuracy of the simulation result is improved.

Description

technical field

[0001] The invention relates to the field of environmental technology, in particular to a gas dynamic distribution simulation method based on a simulation database, a gas dynamic distribution simulation device based on the simulation database, and a gas dynamic distribution simulation system based on the simulation database. Background technique

[0002] With the rapid development of industrial construction and urbanization, the rapid consumption of resources and energy, the atmospheric environment will face unprecedented pressure. Once the harmful gas substance leaks, it may cause great harm to the nearby residents and the environment. Therefore, it is very important to simulate the overall diffusion of the gas through the monitoring results of discrete points, which is beneficial to quickly understand the scope and concentration of the diffusion, so as to formulate effective countermeasures to reduce the harm to residents and property.
