Theoretical and Experimental Studies of Laser-Initiated Detonation Waves forSupersonic Combustion

摘要

Spherical detonations of C2H2/O2/N2 mixtures in an open flow system (initially at1 atmosphere) and planar detonations of C2H2/O2 and H2/O2/C2H2 mixtures in an enclosed tube are successfully initiated by use of an ArF laser at 193 nm. The required critical energy for the initiation of spherical detonations is found to
