Interaction of Laser Pulse with Liquid Droplet
Interaction of laser pulse with gas-droplet mixtures plays an important role in different applications including environmental monitoring of high-risk industrial objects and enclosed spaces, laser ignition of volumetric explosion for application to fire mitigation and design of air-breathing pulse detonation engines. The role of droplets in environmental and engineering applications is two-fold. On the one hand, droplets may pose potential hazard for human activity (erosion of surface and deposition of aerosols in human lungs). On the other hand, they can be successfully used in engineering solutions (to induce working processes in energy systems and to suppress acoustic instabilities of thermal processes). Processes that control transport and combustion of droplets remain unresolved, and introduce significant uncertainties into modeling and simulation. For the optimization of technological processes and for keeping the environment free from droplets, a detailed knowledge of the interaction of laser pulse with individual droplets is necessary.
