Enhancement in laser-induced impulse imparted to a surface in supersonic flow
Abstract
Woodroffe et al. (1980) have observed an increase in the laser-induced impulse imparted to a surface when in a supersonic flow. The present investigation is concerned with an assessment of the effect of supersonic flow on the impulse imparted to a surface by laser irradiation. It is found that near-field enhancement is dependent on the dynamic pressure of the gas, whereas the far-field enhancement is a function of the involved conditions, taking into account the impulse of the impulse per area, blowdown simulation or the real atmosphere, and the type of flow regime. The condition of laser-induced impulse measurements requires a simulation of the flow environment.
