Vertical shaft flue gas series flow simulation device capable of being used for double-hole tunnel

The invention discloses a vertical shaft flue gas series flow simulation device for a double-hole tunnel, which comprises a tunnel main body and a data acquisition system, and is constructed according to a ratio of 1: 18 with a three-lane highway tunnel. The tunnel body is composed of a main frame, a supporting frame, a vertical shaft, a top plate, side plates and partition plates and is divided into a plurality of sections, and one section is a fire source section made of stainless steel. A ventilation system composed of a cross-flow fan and an axial flow fan is arranged inside and outside the main body. The data acquisition system comprises a thermocouple tree, a hot-wire anemometer, an Agilent temperature/wind speed acquisition instrument, a PIV three-dimensional flow field velocimeter and a CO concentration self-recording instrument. The invention has the following advantages: 1) fuel products and flue gas are green and nontoxic; 2) the method can be used for studying the condition and limit that flue gas
