【Abstract】 The five different nozzles are applied to effectively ensure the measurement accuracy over the whole flow rate range in this flow box test-bed. The mobile and lower-noise additional boxes are used to meet the requirement of conversion between inflow-mode test and outflow-mode test. The measurement and control procedure of the test system of this flow box are based on Labview software and both the automatic mode and manual mode are available.更多还原
