Abstract
This work analyzes the fluidic dynamics of the particle extraction function of a nozzle used for the detection of explosives in simulation studies. The nozzle shape with inlet and outlet gas connection is able to extract particles generated by the laser drilling process. Drilling dependent parameters such as the diameter of the generated particles, initial particle velocity, and drilling hole depth are investigated in terms of the residence time of these particles within the extraction nozzle. Besides these, the performance of an applied inlet and outlet gas flow is examined.
