... the rarefaction effects. The effects of finite diaphragm rupture process and partial diaphragm rupture on the flow field and the wave propagations were investigated, in detail. The results show that the shock propagation distance attenuates rapidly for a microshock tube compared to a macroshock tube...

..., a point that was neglected in the earlier theory. The product of αKn * is independent of the characteristic length scales used to define the Reynolds number and the Knudsen number. Therefore, the product of αKn * is a constant for a specified geometry and rarefaction. For closure, the parameters...
