Numerical Analysis of Turbulence Flow Field in Variable Cross-section Air Inlet of Self-regulation Airflow
In order to utilize the technology of pipe flow control, proposing the annular variable cross-section shrink structure. As the radial dimensions of the structure of the inlet has great implications on airflow velocity distribution inner the air inlet, rational size of the air inlet outer diameter and aperture ring gap can make the airflow velocity inner the air inlet develop uniformity quickly. The results show that the smaller size of the air inlet diameter, the airflow velocity uniform distribution develop more quickly. On the other hand, proper size of aperture ring gap can make the airflow velocity inner the air inlet develop uniformity quickly; but when the air inlet is much longer, there is little influence on the airflow velocity uniform development of the outlet. This conclusion has reference value for engineering design and structure miniaturization, and provides the basis for further experimental research.
