Embodiment Construction

[0024] like figure 1 , is a structural schematic diagram of the experimental device used for nonlinear image processing to study the influence of body force on flame characteristics, including the main body of the test bench 1, the glass partition 2, the fan 3, the pulley 4, the weight 5, the tray 6, the steel wire 7, Candle 8, dolly 9, windshield 10 and video camera 11. The main body 1 of the test bench is a rectangular parallelepiped wind tunnel, which is composed of transparent glass and provides a burning space for the moving fire source. The main body 1 of the test bench is closed around and open at both ends, and is separated by a glass partition 2 at the middle section to eliminate the impact on the flame part when the candle moves. A track is arranged at the center of the bottom of the main body 1 of the test bench, and the trolley 9 is placed on the track, and is pulled by a steel wire 7 to realize linear motion. The steel wire 7 goes around 5 groups of pulleys 4 a...

Abstract

The invention discloses an experimental device for analyzing influences of volume force on flame characteristics. The experimental device comprises an experiment table body, two glass partition plates, a draught fan, five sets of pulleys, weights, a tray, a steel wire, a candle, a trolley, a wind screen and a camera. The trolley is arranged on a trolley rail of the experiment table body. The candle and the wind screen are fixed to the trolley. One end of the steel wire is hooked to the front end of the trolley, and the other end of the steel wire is wound around the five sets of pulleys and hooks the tray. The weights are arranged in the tray. The two glass partition plates are mounted in the middle of the experiment table body horizontally. Openings are formed in the two ends of the experiment table body in the length direction. The draught fan is located beside the opening of one end of the experiment table body. The camera is used for shooting the experiment process. The experimental device for analyzing the influences of volume force on the flame characteristics is simple in structure and flexible in operation, and obtained experiment data are true and reliable. The static characteristics and the dynamic characteristics of a diffusion flame structure of a movable combustion source can be researched, and an experiment foundation is laid for researching of the intrinsic physical essence and laws of the flame structure of the movable combustion source.

Description

technical field [0001] The invention relates to a flame characteristic test device, in particular to an experimental device for studying the influence of body force on flame characteristics by a nonlinear image processing method. [0002] Background technique [0003] The turbulent intensity of the surrounding air caused by the combustion of the moving fire source is affected by both the speed of the fire source and the intensity of the combustion, which will lead to a more complex flame structure of the moving fire source. At present, it is still not possible to clearly understand the inherent physical nature and laws of the flame structure of the moving fire source theoretically, and there is no mathematical model to characterize the structure of its flame surface. In recent years, many scholars at home and abroad have used computational fluid dynamics (CFD) methods to conduct many researches on the structural characteristics of flames. Or the flame produced by the motio...
