 Abstract

 

Actually, there are no countermeasures available that can respond quickly and automatically to mitigate the possible consequences of chemical, biological, radiological and nuclear (CBRN) emergencies, even in the presence of fire. For this reason, the European project COUNTERFOG (EUR FP7-312804) arises. The main objective of the present research work is to select materials suitable for the production of new designs of spray nozzles, based on a theoretical study of the stress generated in the process, and an assurance that the materials finally chosen can guarantee the integrity of the system, regardless of the test conditions. As soon as the various models to be studied were established, an adequate selection of materials was made through the CES-Selector program and the stresses generated in the different nozzles were theoretically studied using SolidWorks and ANSYS. These simulations allow for correct selection of materials to guarantee the integrity of the system in operating conditions. Our studies determine that the alloy AA 7075-T6 is a good candidate.

Key words: Materials selection, resistance, fatigue, nozzle.
