- Experimental and numerical study of submerged jets from pipes of different wall thicknesses for Re < 1 M. Sánchez-Rosas Juan Casillas-Navarrete José Alfredo Jiménez-Bernal Vadim N. Kurdyumov A. Medina Física, Astronomía y Matemáticas Low PIV Reynolds velocity measurements number (creeping) flows In this work, the experimental and numerical results from the study of the effects caused in a submerged jet flow by the change in the wall thickness of the circular tube from which said flow originates are presented. For small values of the Reynolds number Re (Re ≈ 0.11), four cases, regarding the ratio of pipe wall thickness to inner radius, are considered: (I) pipe thickness is a fourth of the radius, (II) pipe thickness is half the radius, (III) pipe thickness is equal to the radius and (IV) pipe thickness is three times the radius. The Particle Image Velocimetry (PIV) technique was used to experimentally obtain the velocity and streamlines distributions. A numerical code based on the finite difference method was developed to solve the motion governing equations, and the numerical results were compared with the values obtained experimentally. 2020 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57082931009 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
