Aircraft-Carried Aerosol Sampling Inlet by CFD Simulation

Abstract:

A aerosol sampling inlet has been designed from high-speed aircraft. The objective of the design is to achieving isokinetic and minimizing disturbance for the sampling system. This study was conducted using the CFD code to perform a turbulent simulation of the airflow on the aerosol sampling inlet. The inlet is flown regularly on board an aircraft of Yun-12. The flow rate through the sampling suction tube is a constant value of 100 L/min. The shroud diameter is 150 mm. The diffusion tube inlet and outlet diameter is 35.3 mm. The suction tube diameter is 20.6 mm, which act as transferring aerosol at the velocity of 5 m/s. Results are presented graphically, showing the suction bending radius take 50 mm is more appropriate. It is shown that the diffusion tube slows the sample flow from 40 m/s of the airspeed of the aircraft to approximately 5 m/s. It is suggested that CFD simulation can be useful for improving the optimum aircraft-carried aerosol sampling inlet.
