IFE Thick Liquid Wall Chamber Dynamics: Governing Mechanisms and Modeling and Experimental Capabilities

For thick liquid wall concepts, it is important to understand the different mechanisms affecting the chamber dynamics and the state of the chamber prior to each shot as compared with requirements from the driver and target. These include ablation mechanisms, vapor transport and control, and possible aerosol formation, as well as protective jet behavior. This paper focuses on these research topics and aims at identifying the major issues, assessing the latest results, reviewing the capabilities of existing modeling and experimental facilities with respect to addressing remaining issues, and helping guide future analysis and research and development efforts.
