Optimizing Leading Edge Structure for Aerosol Sampling Diffuser

Abstract:

A diffuser leading edge has been designed for aircraft aerosol sampling. The diffuser leading edge fluid was conducted using the CFD. The diffuser inlet, middle and outlet diameter is 35.3, 100 and 35.3 mm, respectively. The angle of the diffuser inlet and outlet is 4°. The diffuser inlet and outlet with leading edge have achieved isokinetic sampling, and have stable flow and pressure distribution. It is suggested that CFD simulation can be useful for improving the optimum the diffuser.
