Resumo: This study is dedicated to the examination of cavitation-induced erosion, a critical factor in optimizing the efficiency of hydraulic systems, including hydropower plants and pumping systems. To accomplish this, we conducted a sensitivity analysis utilizing a cavitation jet apparatus (CJA) and an experimental configuration that featured a vertical cylindrical test tank, a submerged nozzle, and an aluminum sample (specifically, alloy 6351 T6). The study maintained a consistent standoff distance of 5 cm and an orifice diameter of 2 × 10-3 m. Two distinct nozzle geometries were tested to assess their influence on cavitation erosion. The outcomes revealed that the 20° conical sharped-edges nozzle resulted in the highest erosion rates, while the commercial nozzle (MEG 2510) caused comparatively less erosion. By standardizing the test duration to 1200 seconds and using a cavitation index of 0.14, the researchers avoided overlapping pits. In summary, the CJA, with these adjustments, demonstrated its effectiveness as a tool for evaluating the resistance of solid surfaces to cavitation.

Para isso, realizamos uma análise de sensibilidade utilizando um aparelho de jato de cavitação (CJA) e uma configuração experimental que apresentava um tanque de teste cilíndrico vertical, um bico submerso e uma amostra de alumínio (especificamente, liga 6351 T6). O estudo manteve uma distância consistente de 5 cm e um diâmetro de orifício de 2 × 10-3 m. Duas geometrias distintas de bicos foram testadas para avaliar sua influência na erosão por cavitação. Os resultados revelaram que o bocal cônico com bordas afiadas de 20° resultou nas maiores taxas de erosão, enquanto o bocal comercial (MEG 2510) causou comparativamente menos erosão. Ao padronizar a duração do teste para 1.200 segundos e usar um índice de cavitação de 0,14, os pesquisadores evitaram a sobreposição de poços. Em resumo, o CJA, com esses ajustes, demonstrou sua eficácia como ferramenta de avaliação da resistência de superfícies sólidas à cavitação.Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte2023-12-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/otherapplication/pdfapplication/pdfhttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/1630610.15628/holos.2023.16306HOLOS; v. 5 n. 39 (2023): v.5 (2023)1807-1600reponame:Holosinstname:Instituto Federal do Rio Grande do Norte (IFRN)instacron:IFRNporenghttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/16306/3854http://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/16306/3855Brazilhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessMOHAMMADIZADEH, SEYEDMEHDIDalfré Filho, José GilbertoSampaio Descovi, CassianoMurillo Bermúdez, Luis FernandoAlfonso Sierra, DanielCorzo Perez, Gerald A.2023-12-28T03:14:36Zoai:holos.ifrn.edu.br:article/16306Revistahttp://www2.ifrn.edu.br/ojs/index.php/HOLOSPUBhttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/oaiholos@ifrn.edu.br||jyp.leite@ifrn.edu.br||propi@ifrn.edu.br1807-16001518-1634opendoar:2023-12-28T03:14:36Holos - Instituto Federal do Rio Grande do Norte (IFRN)false
