Simulation of conditions for formation of high velocity microjet flow by pulse laser radiation

The paper studies the formation of a high-speed microjet flow which obtained with optical breakdown in the mode of radiation absorption behind the front of a laser supported driven detonation wave (LDW). Using numerical simulation of the interaction of a series of laser pulses with a subsonic argon jet, the conditions for obtaining a homogeneous high-speed jet and its characteristics are investigated. Ansys Fluent software is used for simulation. In contrast to the generally accepted approach, the calculation model takes into account not only the absorbed power, but also the breakdown plasma impulse in the region of radiation.
