- Abstract
- In this study, the collection efficiency of inertial impactors was numerically simulated by employing the statistical Lagrangian particle tracking(SLPT) model. The SLPT model was proven to be correct in predicting the impactor collection efficiency, when the numerically obtained collection efficiencies were compared with the experimental data of Marple et al.(1987) at normal pressure level and the experimental data of Marjamaki et al.(2000) at low pressure level. Based on the validation results, balloon?borne impactors with the cut?off sizes of 1 ㎛, 2.5 ㎛, and 10 ㎛ were designed. Then, the sampling flowrates of the inertial impactors, required to keep the cut?off sizes constant at different pressures and temperatures, were estimated according to the altitude.
