On the numerical solution of a rising sphere in a Newtonian fluid with temperature-dependent viscosity
Descripción del Articulo
In this work, we present some numerical results about the problem of a rising hot solid sphere immersed in a Newtonian fluid which viscosity depends on the temperature. The model formulated to solve the problem considers two dimensionless parameters: The Peclet number, Pe and a parameter related wit...

El modelo formulado para resolver el problema considera dos parámetros adimensionales: El número de Peclet, Pe y un parámetro relacionado con la viscosidad, e. Las pequeñas y grandes variaciones sobre e conducen a interesantesresultados que son divididas en dos regímenes los cuales presentan una estructura asintótica. Para llevar a cabo los cálculos a fin de resolver el modelo propuesto, el método de elemento finito fue usado junto con una condición de frontera no-slip para la superficie de contacto entre la esfera y el fluído y los resultados fueron comparados a aquellos recientemente mostrados en artículos relacionados en donde la superficie de contacto tiene prescrita una condición de frontera slip.National University of Trujillo - Academic Department of Mathematics2019-12-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://revistas.unitru.edu.pe/index.php/SSMM/article/view/2623Selecciones Matemáticas; Vol. 6 No. 02 (2019): August - December; 140-147Selecciones Matemáticas; Vol. 6 Núm. 02 (2019): Agosto-Diciembre; 140-147Selecciones Matemáticas; v. 6 n. 02 (2019): Agosto-Diciembre; 140-1472411-1783reponame:Revistas - Universidad Nacional de Trujilloinstname:Universidad Nacional de Trujilloinstacron:UNITRUenghttps://revistas.unitru.edu.pe/index.php/SSMM/article/view/2623/2642https://revistas.unitru.edu.pe/index.php/SSMM/article/view/2623/2662Derechos de autor 2019 Selecciones Matemáticasinfo:eu-repo/semantics/openAccessoai:ojs.revistas.unitru.edu.pe:article/26232022-10-21T18:52:01Z |
