Problems solved by technology

In general, the temperature in the troposphere decreases with the increase of altitude, but due to the influence of meteorological and topographical conditions, sometimes the temperature increases with the increase of altitude.
Due to the existence of the temperature inversion layer, the upper part of the atmosphere is hot and the lower part is cold, which hinders the development of the vertical movement of the air, causing a large amount of smoke, dust, pollutants, wate

Embodiment Construction

[0035] The present invention will be further described below in conjunction with accompanying drawing.

[0036] see figure 1 , the present invention comprises the following steps:

[0037] Step 1, according to the velocity of the artificial jet, the artificial jet is defined as a compressible flow region when the flow Mach number is greater than 0.3 within a certain height range along the center line, and as an incompressible flow region when the flow Mach number is less than 0.3;

[0038] Step 2, simulating the compressible flow region through the turbulence model, and obtaining the density-based flow field transient equation in the compressible flow region;

[0039] Step 3: Simulate the incompressible flow region through the turbulent flow model, and obtain the flow field transient equation of the incompressible flow region through the steady-state solution based on pressure;

[0040] Step 4: Combining the flow field transient equations in the compressible flow region and ...

Abstract

The invention discloses a method for calculating the range and strength of an artificial airflow disturbance temperature inversion layer in a small scale. According to the invention, the flow of the artificial jet flow in the atmosphere is divided into compressible flow and incompressible flow; flow field transient equations of a compressible flow area and an incompressible flow area are calculated respectively; the range and the strength of the artificial jet disturbance inversion layer can be known; the method can accurately calculate the disturbance range and intensity of the thermal inversion layer under a small scale, can provide a set of overall solution for cloud and mist removal of airports, bridges and expressways and treatment of urban atmospheric pollution, and has the advantages of being low in cost, flexible to use, obvious in effect and the like compared with other treatment modes.

Description

technical field [0001] The invention belongs to the field of measuring and calculating the disturbance range of an inversion layer, and in particular relates to a method for calculating the range and intensity of an artificial air flow disturbing a temperature inversion layer in a small scale. Background technique [0002] The temperature inversion layer refers to the layer in the troposphere where the temperature increases with altitude. In general, the temperature in the troposphere decreases with increasing altitude, but due to the influence of meteorological and topographical conditions, sometimes the temperature increases with increasing altitude. Due to the existence of the temperature inversion layer, the upper part of the atmosphere is hot and the lower part is cold, which hinders the development of the vertical movement of the air, causing a large amount of smoke, dust, pollutants, water vapor condensate, etc. It is above cities and industrial areas. Due to the man...
