Determinación del campo de velocidad en una válvula magnetoreológica con efecto de deslizamiento hidrodinámico

Abstract

El presente trabajo analiza el comportamiento de una válvula magnetoreológica (MR) en presencia de un campo magnético aplicado. Se asume que el fluido MR modifica su comportamiento reológico a partir del esfuerzo de fluencia, resultando en un flujo con una combinación entre una fase sólida y líquida. Para simular este fenómeno de flujo, se utiliza el modelo de Herschel-Bulkley con las ecuaciones gobernantes descritas por las ecuaciones de continuidad y de cantidad de movimiento para un fluido incompresible. En el análisis se considera que las paredes del conducto que forman la válvula MR han sufrido desgaste y, por tanto, se presenta un deslizamiento hidrodinámico. Los resultados se presentan en función de perfiles de velocidad que dependen de los parámetros adimensionales que surgen del modelo matemático. Estos son el gradiente de presión, el esfuerzo de fluencia, el índice de ley de potencia, la razón de viscosidad y el deslizamiento hidrodinámico.
