Abstract

The invention relates to a fuming device, especially to a fuming device of a smoke wind tunnel. The fuming device is provided with a fuel tank breather pipe, a fuel tank, an oil delivery hose, a smoke oil controller, positive and negative clamps, power supply positive and negative wires, positive and negative binding posts, a wind tunnel test section hole body, a metal wire, an insulation connecting wire, a smoke oil collector and a direct-current high-voltage power supply. The oil tank is connected with the metal wire by the oil delivery hose; the fuel tank breather pipe is arranged at the top of the oil tank and is connected with the air; and the smoke oil controller is installed on the fuel tank breather pipe between the oil tank and the metal wire. The oil delivery hose and the metal wire are connected to the two ends of the positive binding post respectively; and the positive binding post is fixed at the opening part of the top of the wind tunnel test section hole body. The metal wire and the insulation connecting wire are connected to the two ends of the negative binding post and the negative binding post is fixed at the opening part of the bottom of the wind tunnel test section hole body. The power supply positive and negative wires are connected with the positive and negative clamps; and the positive and negative clamps are clamped at the naked part where the positive and negative binding posts and the metal wire are connected. And the bottom of the insulation connecting wire is connected with the smoke oil collector.

Description

technical field [0001] The invention relates to a smoke generating device, in particular to a smoke generating device in a wind tunnel for low-speed wind tunnel smoke flow continuous display experiments. Background technique [0002] In the teaching and scientific research of fluid mechanics, the smoke tunnel is often used to conduct flow display experiments on the fluid motion state. The flue gas tunnel vividly reflects the flow state of the gas around the experimental model through the change process of the plume. [0003] The commonly used smoke generation method in the wind tunnel is to heat the e-liquid outside the wind tunnel, and then introduce the generated smoke into the wind tunnel; or place a metal wire upstream of the experimental model, and apply the e-liquid on the wire. Oil droplets are formed by tension and hung on the metal wire, and then the metal wire is energized, and the temperature of the metal wire with a certain resistance rises after being energized...
