Abstract

The invention provides a thermally-driven fire whirlwind simulation experiment device. The experiment device comprises an experiment device body and a liquid level constant maintaining mechanism; the experiment device body comprises an experiment table and a fire whirlwind simulation frame mounted on the experiment table, and the experiment table is provided with a mounting position for mounting a combustor; the liquid level constant maintaining mechanism comprises a liquid supplementing pool and a liquid storage pool for continuously supplementing liquid to the liquid supplementing pool, and the liquid supplementing pool is provided with an overflow port; and the liquid supplementing pool is communicated with the combustor through a connecting pipe. According to the thermally-driven fire whirlwind simulation experiment device, fuel can be supplemented into the combustor in real time through the liquid level constant maintaining mechanism, the fuel liquid level is maintained to be constant, and the combustion rate of fire cyclone is accurately calculated.

Description

technical field [0001] The invention belongs to the technical field of fire whirlwind simulation experiments, and in particular relates to a heat-driven fire whirlwind simulation experiment device capable of maintaining a constant fuel liquid level in real time. Background technique [0002] Fire whirlwinds are common in forest grassland fires and forest-urban interface fires, and are an extreme fire phenomenon induced by the mutual coupling of combustion and surrounding rotation. The burning rate, radiant heat flow, flame height and other characteristic parameters of the fire whirlwind are higher than those of ordinary buoyant pool fires, and the violent rotation speed of the fire whirlwind can lift the surrounding combustibles to induce flying fires to generate new ignition sources, thereby accelerating the spread of fire. Therefore, it is necessary to carry out research on the combustion and flow laws of fire whirlwinds to provide reliable theoretical support for the prev...
