Estudo da utilização de conceitos biomiméticos no perfil hidrodinâmico NACA 4412
(Universidade Federal de Santa Maria, 2023-02-09)
Brazil is one of the great countries that generate electricity through hydraulic energy. In a
hydroelectric power plant, the hydraulic turbines are the only ones responsible for transforming
hydraulic energy into mechanical ...
Avaliação da influência da vazão de gás utilizada no processo GMAW nas tensões residuais utilizando ondas LCR
(Universidade Federal de Santa Maria, 2023-03-09)
Welding is a manufacturing process widely used in industry to join metal parts permanently.
