detonation simulation of gas mixutre(H2:O2:AR=1:1:7) at temperature 298K and pressure 6670Pa.
clear and detailed triple point structures are obtained

either pressure contours and temperature contours can provide detailed structures of flow field

here is the pressure contours at t=239.94us,the regular detonation cells can be seen clearly from the pressure contours.Acoording to the classification of detonation,it should belong to ordinary detonation which poessesses smaller detonation cell size than marginal detonation

what is the triple point ?

triple point is the intersection of three shocks:incident shock,mach stem and transverse wave

thank you very much! But what does that point mean?

the triple point plays an important role in the formation of regular structure in the flow field of gas mixture detonation.Actually the triple point is not the unique point for flow field of gas mixture detonation,the terminology is borrowed from gas dynamics.

请问您用的是什么求解器？CFX还是Star－CD？能把网格和solution show给我们吗？
