Pretty much any spark, from the static shock you get from touching a doorknob to the giant bolts that light up Jupiter's turbulent atmosphere, could be considered lightning, he said.
The results show that the shock wave structure is unsteady in shock induced hypersonic turbulent separated flows, generating an intermittent region.
结果表明：在激波诱导的高超音速湍流分离流中，激波结构是不稳定的，产生一个间歇区域。

It is shown by calculation and analysis that the main form of the interaction in compressor cascades is the interaction between shock wave and turbulent boundary layer in channels.
