The Test And Evaluation Of Characteristic Of Aerodynamics On Portable Erosion Wind Tunnel

Using a portable wind-tunnel to carry on research of open-air wind erosion is one of crucial way of investigation of wind erosion issue. This text according to the thought of modern test technological theory, on the basis of configuring the hardware test system of the aerodynamics characteristic in the wind-tunnel system, applying LabVIEW to develop a suit of software system to carry out data acquisition ,analysis and process portable wind tunnel usage in the universal computer, the system can finish the main characteristic parameters testing of field aerodynamics flows in the portable wind-tunnel (including the testing of turbulence intensity and distribution of the different height or section, air airflow stability test, air current horizontal homogeneity test, test of air velocity equality, pressure gadient on the direction of axis, wind-tunnel energy ratio test).This text has also finished testing the measurement thickness of boundary layers on wall border of baseplate and side under the terms to the cavity of wind-tunnel of portable wind-tunnel and the debugging method of wind-tunnel simulation atmospheric boundary layers of central wind speed profile test,offer the reference data for inspection of the wind-tunnel of portable wind-tunnel.
