After the air-flow of the import of the air-flow and the second tube body 120 of the import of the first tube body 110 converges at point
Turbulent flow 10 and whirlpool 20 will be formed.According to Bernoulli's theorem, if the sectional area and remittance of the first tube body 110 and the second tube body 120
Pipeline area after conjunction is equal, then will accelerate to flow after gas converges, simultaneously because the presence of angle, causes the first tube body
Flow separation will on the corner occur for the air-flow of 110 air inlets, and the air-flow of 110 air inlet of the first tube body is under the action of inertia
Most of gas is pushed to the right side of pipeline, causes to converge rear pipeline right side gas flows flow velocity height, left side air-flow velocity is low, viscous
Under shear action, the air-flow on right side will drive left gas that flowing is accelerated to form vortex.The presence of vortex will consume a large amount of
Energy add pipeline energy of flow loss, so as to add import with outlet pressure differential.
