Gas standing wave determination experimental device

Abstract

The invention discloses a gas standing wave determination experimental device and belongs to the technical field of gas standing wave determination experiment. A standing wave tube is a transparent tube; a first loudspeaker and a second loudspeaker are arranged in the standing wave tube respectively; the sound wave emitting surfaces of the two loudspeakers are opposite to each other and are perpendicular to the axial center line of the standing wave tube respectively; the first loudspeaker is in fixed seal fit with the standing wave tube; the second loudspeaker is in sliding contact fit with the standing wave tube; the two loudspeakers are connected with a signal generator respectively; a graduated scale is arranged on the outer tube wall, parallel to the axial center line of the standing wave tube, of the standing wave tube; the zero-point graduation line of the graduated scale is positioned on a plane where the sound wave emitting surface of the first loudspeaker is located; a plurality of pressure sensors are arranged on the outer tube wall of the standing wave tube, are uniformly distributed along the axial center line of the standing wave tube, are hermetically communicated with an inner tube cavity of the standing wave tube and are connected with a computer; a smoke inlet is formed in the tube wall of the standing wave tube between the two loudspeakers; a smoke outlet of a smoke generator is communicated with the smoke inlet of the standing wave tube.

Description

technical field [0001] The invention belongs to the technical field of gas standing wave measurement experiments, in particular to a gas standing wave measurement experimental device. Background technique [0002] The gas standing wave phenomenon is a phenomenon that often occurs in real life, but it is often ignored by people. Because the gas standing wave phenomenon is difficult to observe, in order to observe the gas standing wave phenomenon, relevant technical personnel have designed a device for observing the gas standing wave phenomenon. The demonstration experiment device of the wave phenomenon, but this demonstration experiment device has a single function, and can only complete the demonstration of the gas standing wave phenomenon of flammable gases, but the display effect is not good when demonstrating the gas standing wave phenomenon, and it is difficult to pass the demonstration experiment The device can accurately test the principle of gas standing wave phenomen...
