Two-in-one simulation device of tornado and downburst and simulation method thereof

Abstract

The invention discloses a two-in-one simulation device of tornado and downburst. The two-in-one simulation device comprises a center wind channel, first flow guide wind channels and second flow guidewind channels, wherein a simulation fan is mounted in the center wind channel; wind inlet ends of the first flow guide wind channels are connected with a wind outlet end of the simulation fan; wind outlet ends of the first flow guide wind channels are connected with a wind inlet end of the simulation fan; a first valve is arranged between the wind inlet end of each first flow guide wind channel and the wind outlet end of the simulation fan; a wind inlet end of each second flow guide wind channel is communicated with the wind outlet end of the simulation fan; a second valve is arranged betweenthe wind inlet end of each second flow guide wind channel and the wind outlet end of the simulation fan; a second wind inlet channel located between the wind inlet end of the simulation fan and the wind outlet end of each first flow guide wind channel is arranged in the center wind channel; a third valve is arranged in each second wind inlet channel; and a fourth valve located among the second wind inlet channels and the wind inlet ends of the first flow guide wind channels is arranged on the center wind channel. The invention also discloses a simulation method using the two-in-one simulationdevice of tornado and downburst.

Description

AI Technical Summary

Problems solved by technology

When it is necessary to simulate a downburst after simulating a tornado in a wind tunnel test, the tornado simulator needs to be removed and replaced with a downburst simulator, resulting in longer test intervals and complicated operations; Installing a tornado simulator and a downburst simulator at the same time will lead to an increase in investment costs
