We performed a numerical investigation of the process 
of transition of a spherical leading front into a plane one in a cylindrical 
channel. The processes of the collision of reflected shock waves, 
formation of a nonstationary grating-like structure of flow, and of 
the overtaking interaction of shock waves are investigated. We found 
that in the presence of hot gas layers on the walls of the channel 
a plane head front is not formed.
