In this study the fluid flow and particle trajectories for a tube sampler are investigated numerically. The flow around the sampler is assumed to be inviascid and, using a mathematical approach, flow characteristics are determined. The paths of the particles in the fluid are then traced and the aspiration efficiency of the sampler is investigated. Numerical results for the sampling efficiency are obtained over a large range of parameters and they are found to be in good agreement with related empirical work. In order to give a general guide on the sampling efficiency of a tube sampler, new empirical formulas for both the aspiration coefficient and the overall aspiration efficiency are developed based on extensive numerical calculations. |
