A Calculation Method of High Pressure Air Resource Consumption in Wind Tunnel Group

Abstract

The present invention is applicable to the technical field of wind tunnel test, and provides a method for calculating the consumption of high-pressure air resources in a wind tunnel group, which includes the following steps: constructing a topology model; establishing a monitoring system; collecting the status of the wind tunnel being tested in the wind tunnel group , collect the state of the high-pressure air system; obtain the pressure difference of the tank group consumed by the wind tunnel being tested; update the topology model; traverse the updated topology model to obtain the guaranteed volume of the wind tunnel being tested; calculate the wind tunnel being tested by the differential pressure method The high-pressure air resource consumption of the cave; the high-pressure air system includes a high-pressure unit, a high-pressure tank group, a main gas pipeline, gas pipelines, and valves. The present invention expresses the actual physical topology relationship between the high-pressure air system and the wind tunnel by building a model. Therefore, the calculation method of the high-pressure air resource consumption of the wind tunnel group in the embodiment of the present invention can automatically identify The high-pressure tank group, gas main pipe, and gas branch pipes in use in the wind tunnel.

Description

A calculation method for high pressure air resource consumption in wind tunnel clusters technical field The invention belongs to the technical field of wind tunnel test, particularly relate to a kind of calculation method of high pressure air resource consumption of wind tunnel group Law. Background technique Large-scale wind tunnel equipment and facilities are important national strategic resources, aerospace, ground transportation, building bridges, Wind tunnel tests are required in many fields such as renewable energy and environmental protection. According to the gas velocity in the cave, wind tunnels are generally divided into Low speed, high speed, ultra-high speed and other types, each type of wind tunnel is divided according to the diameter of the test section, test type, test time, etc. The points are further divided into large / small, conventional / special (such as icing, acoustics, low temperature, etc.), transient / continuous and other different wind tunnel...
