Experimental Evaluation of the Factors That Influence Cylindrical Water Projection Devices against IEDs 2023 Access copy available to the general public Unrestricted Terrorists usually employ Improvised Explosive Devices (IEDs) to cause maximum damage with a single action, in asymmetric war scenarios. In the counter-terrorism fight, bomb disposal specialists have to combat these instruments by safeguarding their lives, avoiding fortuitous IED explosion, and preserving evidence of the device that could lead to the capture of the perpetrators. Some very effective deactivation tools that combine these features are high-speed water-explosive projection devices. To understand and quantify the impacts of the many factors that intervene in their operation and effectiveness, extensive experimental tests should be conducted. However, Operations Research techniques allow robust results to be obtained by minimizing experiments. This study focuses on the use of Design of Experiments (DoE), with a factorial experiment plan divided into two levels, to analyze the influence of the amount of explosive, the diameter of the device (that is, the mass of water to be projected), the density of the water, the distance at which the IED is located, and the resistance of the inner tube material. Results show that the mass of explosive, the diameter of the device, the interaction of the mass of explosive and the density of the water, and the interaction between the resistance of the inner tube and the diameter of the container have a strong influence on the speed of projected water. info:eu-repo/grantAgreement/ES/UZ/CUD2020-21 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.5 2023 ENGINEERING, MULTIDISCIPLINARY 44 / 181 = 0.243 2023 Q1 T1 PHYSICS, APPLIED 87 / 179 = 0.486 2023 Q2 T2 CHEMISTRY, MULTIDISCIPLINARY 115 / 231 = 0.498 2023 Q2 T2 MATERIALS SCIENCE, MULTIDISCIPLINARY 258 / 439 = 0.588 2023 Q3 T2 0.508 2023 Engineering (miscellaneous) 2023 Q2 Fluid Flow and Transfer Processes 2023 Q2 Materials Science (miscellaneous) 2023 Q2 Instrumentation 2023 Q2 Process Chemistry and Technology 2023 Q3 Computer Science Applications 2023 Q3 5.3 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Otón-Martínez, Ramón A.
