Numerical simulation investigation of the internal flow field for wind tunnel
Numerical simulation was applied to study the flow field in the wind tunnel. Two different combinations for nozzles were analyzed, and the characteristic of flow filed for several different rectifier thicknesses (5mm, 10mm and 15mm) in the wind tunnel were also compared. The results show that, under the same inlet velocity, the velocity of airflow after the second rectifiers for adjacent opening nozzles is larger than those for diagonal opening nozzles. However, diagonal opening nozzles made the subsequent flow field more uniform and smooth. Furthermore, with the increase of rectifier thickness, the flow filed after the second rectifier appears much more even.
