Electromagnetic velocity gauge: use of multiple gauges, time response, and flow perturbations

摘要: We have developed an in-situ electromagnetic velocity (EMV) gauge system for use in multiple-gauge studies of initiating and detonating explosives. also investigated the risetime manner which it perturbs a reactive flow. report on special precautions that are necessary multiple experiments to reduce lead spreading, simplify target fabrication problems minimize cross talk through conducting explosive. Agreement between measured stress records calculations from data give us confidence our gauges recording properly. used laser interferometry measure polymethyl methacrylate (PMMA). To resolve difference two methods, we examined hydrodynamic material rate effects. In addition, considered effects shock tilt, electronic response magntic diffusion gauge's time.
