Abstract

The invention provides a device and a method for studying the influence of external wind speed on flame propagation and stability. The device comprises a fan, a wind quantity adjusting panel, a wind speed uniform distribution panel, an experiment tunnel, a wind speed measurement window, a smoke measurement window, a draught fan, a support, a Bunsen burner, a height adjusting stand, a rubber tube, a flow meter, a valve and a gas cylinder. One end of the experiment tunnel is used for wind supply and the other end is used for wind inducing, so that the propagation characteristic and the stability of flames of a fixed fire source can be studied on the condition of uniform external wind speed. The device is low in manufacture cost, simple in structure, convenient to operate and flexible to control; experimental phenomena are easy to observe and measure; obtained data are real and reliable; experimental basis can be provided for studying the flame structure and the burning characteristics under the condition of relative motion and analyzing the propagation characteristic and the stability of flames.

Description

technical field [0001] The invention relates to the experimental technical field of the influence of external wind speed on flame propagation and stability, in particular to a device for studying the influence of external wind speed on flame propagation and stability. Background technique [0002] The characteristics of flame propagation and its combustion stability have always been one of the research hotspots of many scholars at home and abroad. By studying the flame combustion characteristics of controllable combustion, we can understand the development conditions of fire source diffusion combustion and its combustion propagation process, so as to further deduce the formation and development laws of fires and other processes in the state of uncontrolled combustion, which can effectively reduce fires. To provide the necessary theoretical basis and experimental basis for the harm caused to human society. [0003] When a relatively stationary fire source burns, the flame un...
