Considering the existence of reflection effect
of pipe terminal, the peak overpressure near the end will
depend on the comprehensive effect of these factors. The peak
overpressure of 100 nm aluminum powder is 574.97 kPa at the distance
of 766 cm from ignition point, while that of 75 lmaluminum
powder is 62.102 kPa, which is far less than that of 100 nm aluminum
powder. The variation law of peak overpressures of various
concentrations is the same, and the variation law of peak overpressures
of 100 nm aluminum powders is similar to that of 75 lm aluminum
powders.
