Example 1
Fig. 1 shows the structural schematic diagram of this embodiment. In this embodiment, the single door I(1), the single door 11(12), the single door 11{13), the double door 114}, the double door II (22) and the single door IV (23) remain open; The upper and lower sides of the collector of the large test wind tunnel are connected with the left wall(2) through the air deflector (3); The outlet diffusion section | (11) of the large test wind tunnel is connected with the right wall (2) through the air deflector (3); The upper and lower ends of the double door | (14) are connected with the right wall (2) through the air deflector(3); The upper and lower ends of the double door
II (22) are connected with the left wall (2) through the air deflector (3), and the two test wind tunnels are spaced apart to form a double straight-through test wind tunnel; Here, the experiments of wind-blown sand movement, sand dune formation and evolution, control of soil wind erosion, prevention and control of engineering sand damage, plant physiology and ecology changes, etc. are carried out.
During the operation of the large test wind tunnel, the external wind passes through the collector | (4), the power section | (5), the diffusion section | (6), the stabilization section | (7), the contraction section | (8), the test section | (9) and the outlet diffusion section | {11) from the left side of the wall (2) in turn, and finally is discharged from the right side of the wall (2).
During the operation of the small test wind tunnel, the external wind passes through the collector | (15), the power section | (16), the diffusion section | (17), the stabilization section (18), the contraction section | (19), the test section | (20) and the outlet diffusion section | (21) from the right side of the wall (2) in turn, and finally is discharged from the left side of the wall (2).
Example 2
Fig. 2 shows the structural diagram of this embodiment. In this embodiment, when the single door I(1) and the single door I(12) are closed, the single door 1(13), the double door I{14}, the double door 1{22) and the single door IV (23) remain open. The upper and lower ends of the double door | {14) are connected with the right wall (2) through the air deflector (3); The upper and lower ends of the double door II (22) are connected with the left wall (2) through the air deflector (3), forming a single through wind tunnel test.
During the operation of the small test wind tunnel, the external wind passes through the collector | (15), the power section | (18}, the diffusion section | (17), the stabilization section (18), the contraction section | (19), the test section | (20) and the outlet diffusion section | (21) from the right side of the wall (2) in turn, and finally is discharged from the left side of the wall (2).
At the same time, when the double-door | (14) and the double-door Il (22) are closed, the enclosed space where the small test wind tunnel is located can form an independent climate simulation test room, which can reduce the restricted range of wind tunnel test by simulating the climate environment in different regions and at different times.
Example 3:
Fig. 3 shows the structural diagram of this embodiment. In this embodiment, the single door | (1), the single door Il {12}, the single door Ill (13) and the single door IV (23) remain closed, while the double door 1(14) and the double door II (22) remain open. The wind deflector (3) is arranged in an arc shape, connecting the upper end of the collector [(4) with the left side of the wall body (2), connecting the lower end of the collector [{4) with the upper end of the double-door Il (22), connecting the lower end of the double-door II (22) with the left side of the 5 wall body (2), connecting the upper end of the outlet diffusion section | (11) with the lower end of the double-door [(14), thus forming a double-through closed-loop wind tunnel.
During the test, the incoming wind enters the large test wind tunnel from collector | (4), and can be accelerated in the power section | (5) of the large test wind tunnel according to the test wind speed, and the outlet diffusion section | (11) enters the annular channel formed by the air deflector (3) on the right. Then, it enters the collector 11(15) of the small test wind tunnel through the annular channel on the right side, and secondary accelerate in the power section II(16) of the small test wind tunnel, discharged from the outlet diffusion section 11(21), and enters the collector 1(4) of the large test wind tunnel through the annular channel formed by the air deflector (3) on the left side, and is accelerated again in the power section I(5); cycle back and forth in turn until the wind speed meets the test setting requirements.
Through the cyclic acceleration of two test wind tunnels, the overall functional loss can be reduced under the condition of obtaining higher test wind speed, and different tests can be carried out in two wind tunnels under same wind speed, thus speeding up the overall test process and shortening the test time.
